I walked into my local Radio Shack store to purchase a set of joysticks for my CoCo 2. As I wrote my check, the store mananger handed me the September issue of the rainbow and told me to have a ball. It was my first meeting with THE RAINBOW, and I did have a ball. I went home and sat right down and entered Color Ball. I am a 55-year-old kid at heart and the games fas- cinate me. I sent for the two most recent game issues and I am literally having a ball. Thank you. I found my pot-o-gold. Ray Atwood Naranja. Florida Support for the Community Editor: With regards to Jim Price's criticism of your OS-9 articles in the September issue, I think his suggestion that you ignore OS-9 is ludicrous. OS-9 is a major part of the CoCo Community and without it the CoCo, and THE RAINBOW itself, might have died long ago. We should not have to purchase an- other magazine for OS-9 articles, as he suggests, when OS-9 is such an important part of the CoCo. Moreover, his suggestion ignores the financial contribution OS-9 vendors make to THE RAINBOW through advertisements. The reduction in size of THERAINBOW is due not to OS-9 as he implies but to de- creased revenue from advertisers. This is caused in part by people like Mr. Price who do not buy THE RAINBOW and do not sup- port it or its advertisers. If Mr. Price wants "good useable mate- rial,"! suggest he support THERAINBOW, as well as its advertisers, and try OS-9. Once he sees the power of OS-9 he may develop an interest in it just as I did. Bruce Arsenault Cleveland. Nova Scotia Canada The Educated CoCo Editor: I am a gullible 63-year-old woman, but I don't believe what just happened on my CoCo 3. 1 was using your hint in the January 1987 issue (Page 148) to make print-outs of disk directories. I got tired of all the typing required for each disk, so I typed: 10 POKE 111. 254:DIRand then used RUN. By mistake, I used it on a DOS disk and got some lines of garbage. When I used it on my next disk, the directory listings were underlined. This was even better and easier to read, but I couldn't figure out what had happened. Being nosy, I listed my original line 10 and this is what I saw; 10 POKE 111.254:DIR 20 FOR N-&H16128 to &H20480 Where did Line 20 come from and what does it mean? Is my beloved CoCo 3 taking over the tedious job of programming to save my arthritic fingers? Do you think it might eventually write a program for win- ning the Florida State Lottery? Please explain. Mrs. Dorothy Topping 3400 S.W. Dunklin Avenue Okeechobee, PL 34974 To avoid a lot of technical jargon, the gohhledegook on the DOS disk dinged the BASIC interpreter. This flaked your pro- gram and sent some codes to the printer telling it to underline. (You can probably duplicate this by sending the codes your- self ) It isn ' t a miracle cure for arthritis , but we suppose this random happening could result in a winning lottery number. Powerful Connections Editor: Is it possible to modify a CoCo 3 for use with the British 240-volt, 50-Hz power sup- ply and 625-line PAL TV standard using the RF modulator and transformer from a CoCo 2 sold in Britain? If so, how would I do this? Are there any companies that would make the modification for me? PR. Marlow 50 Lime Avenue Bentley. Walsall West Midlands, G.B. WS2 OJP For information on using the CoCo over- seas, refer to "CoCoing Abroad" (November 1987, Page 32) by Marty Goodman and Don Hutchison. The CoCo Supports Him Editor: I'm a handicapped technician and I can't justify the expense of expanding my Tandy hx. In fact, my printer stays pretty much switched to my CoCo.

Maybe I can soon afford OS-9 and learn more Unix-type skills. I love this 5 1 2K CoCo 3 system . I bought CoCo Max 3, Max 10, Color Graphics Designer Plus and Simply Belter. I use them daily, along with several rainbow programs that I've modified. I keep an 800- item wordbase inventory under Simply Bel- ter that is more flexible and much faster for my uses than dBASE or Unix. I'd rather put my dollars in this CoCo. I've got a family, bills and little time for fooling around. I wish Radio Shack treated me a little better for the money I've spent. And I wish IBM vendors were as good as the CoCo's. I think what some clerks call "their kid's computer," in addition to my sub- scription to THE rainbow, gives me the biggest bang for the buck on this planet. Michael Cormier Ft. Myers, Florida Upgrading the CoCo Editor: I want to buy a disk drive for my CoCo 3 and to upgrade the memory to 512K (it now has 128K). At present I use a tape recorder to store my programs. I want to order my disk drive out of the rainbow. I really enjoy reading THE RAINBOW and want to order RAINBOW ON DISK. What is the size of the disk? Could you tell me what is compatible with my CoCo 3 in the line of a disk drive and upgrade kits. Bemiie Luttrcll 314 Bird Circle Greeneville. TN 37743 RAINBOW ON DISK is produced on 5'U-inch floppies. Several advertisers in THE RAIN- BOW offer 5 l U-inch, Drive systems. Just compare the prices. Similarly, the 5I2K upgrade is fairly standard from advertiser to advertiser. For specifics on upgrades, see "Upgrading the Color Computer's Memory" by Marty Goodman in the March 1989 issue. The Great MPI Hunt Editor: Radio Shack in Fort Worth suggested you might be able to help me locate a Multi- Pak Interface (Cat. #26-31 24). I understand it is needed to operate my old disk drive with a new CoCo 3. I would appreciate having a list of your vendors that could help me in such a search. Thanks. Robert Heyl 8983 Eash'iew Drive Allison Park. PA 15101 Yes, the MPI is a difficult animal to locate. Check with Computer Plus to see if they can help you out. Or perhaps another reader can solve the problem for you. Looking to Ham it Up Editor: I am in desperate need of locating soft- ware for the CoCo to manage my ham shack. I had a CoCo 1 that I used for rtty about five years ago. In the last four years I put hamming and computing aside to pursue my trade as an ironworker. I re- cently became active again with both hob- bies. After much debate with and ridicule from other hams. I decided to buy the CoCo 3 rather than an IBM. For some unknown reason I wanted to support the CoCo. I now have a CoCo 3 (512K), two floppy drives and OS-9, but I have very little software for the ham radio. I need to locate more ham software and would like to interface my Kenwood 440 transciever to my CoCo. I feel I've done my part to support the CoCo. Now will the world of CoCo please help to support me? Any information on this mat- ter would be appreciated. Perhaps you could help me locate Steven Ford and any other ham-CoCo enthusiasts. Dean Maluski 27 William Street New Britain. CT 06051 As published in the February 1990 issue, Steven Ford can be contacted at 12 Fox- bridge Village Road, Branford, CT 06405. Another source of ham information is Dale Puckett, author of "KISSable OS-9." Protecting Protection Editor: I read about the Reset protection routine in the July 1990 issue of THE rainbow and at the time thought "I won't need that.' Of course now I need to use Reset pro- tection. I also need a Break/Escape protec- tion routine as well as the ability to restore all of these functions without turning off my CoCo 3. I am developing a password protection scheme, but it only protects one program. I would like to modify this so that my password will protect an entire disk from unauthorized access. Any helpful hints and advice will be welcome. Joan Claso 2480 Lazy Landing Drive Redding, CA 96002 68000s Unite! Editor: I recently attended a computer fair at Purdue University where I gathered infor- mation about Amiga, Macintosh and MS- DOS-based systems. When I looked through the information about the Amiga and Macintosh systems, I noticed these sys- tems use the 68000 and 68030CPUS, similarto the new 68K OS-9 systems offered in THE rainbow. I wonder if these systems have any similarities and, if so, is there any compatibility between them. I want to purchase a new system, but fear I might be leaving the CoCo family. Is there any hope? Kevin Bump 741 San Ricardo Drive Greenwood, IN 46142 There are myriad hardware differences ben\'een the Macintosh, the Amiga and the computers on our horizon. Still, OS-9 pro- vides a good foundation for compatibility, and OSK (OS-9 for the (>8000 series) is avail- able for all these machines. SoundTrax Update Editor: I've received a few letters from people having trouble booting their SoundTrax disk. It seems that some older drives tend to be unreliable and have problems with the SoundTrax loader. For this reason we have slightly reprogrammed the loader to be a little more understanding of these drives. While we were modifying the loader, we decided to make a few other suggested changes. First, the program can now be booted from any drive instead of the nor- mal hard-coded Drive 0. It also recognizes double-sided drives so you can access drives 2 and 3 as the flip sides of and I.Forthose who have purchased SoundTrax either through us or a dealer and have the afore- mentioned booting difficulties, or simply want to upgrade to Version 1.01 with the minor additions, please send the original disk along with your receipt and $5 to cover time and S/H. We will rush the upgraded disk to you. Thank you. Glen R. Dahlgren Sundog Systems ■ Manassas, Virginia Kudos Editor: It may be of interest to you that, as a result of your publication of my letter in the May issue I have received replies not only from some American readers, but also from Brazil and Australia. Here is a quote from your Brazilian reader: "Unfortunately, the CoCo (compatibles) ■ was discontinued here in Brazil and the only support for us is through the THE rainbow.

Just a few minutes ago I finished reading Allen Drury*s new novel Toward What Bright Glory?, the first in a series of novels expected to follow a group of college stu- dents from the year just before World War II to the present day. Drury is excellent at writing series novels, and his first work in this series holds much promise. I hope when I write my long-planned novel I can create as thought-provoking a title as this former Pulitzer Prize winner (for Advise and Consent) has here. This book's title and the book itself, including the final paragraphs from which the title comes, have universal appeal. Even though Drury writes about the issues of war and peace, the shaping of lives, the maturing of people and of nations, his title is one that can apply to almost any human endeavor. As I finished reading the final page and reluctantly closed the book (already wish- ing for the second one), I thought about our own CoCo Community. In this book the class of '39, merely three months from the bosom of their university, came face-to- face with what Mr. Drury terms "the hounds of hell" unleashed on the world by the fanatic Nazi Germany. We, in the CoCo Community, are also sometimes beset by trials of our own. While our issues may not be as world-shattering as those in Dairy's book, they are nonetheless important to those affected. And even though we are not under siege from a foreign power, my mail indicates a perception that our Commu- nity's way of life is no less threatened. I do not see this threat. We are the possessors of an amazingly sophisticated computer system. We are embraced by a caring and interested Com- munity. There are new options on the hori- zon with more powerful machines that will allow us to '"Keep on CoCo-ing." And a growing number of small developers who need our encouragement. Ours is an an- cient (as computers go) and proud heritage on which we can only improve. Toward what bright glory do we aspire? To use our CoCos, to pass them on to others and to share our information and knowl- edge. All of these are possible for each of us. And for our CoCo Community as well. I must address some of the concerns expressed recently in my mail. I realize mail is not necessarily an accurate reflec- tion of a total Community, but often those who voice their concerns speak for many others who are no less concerned but choose to remain silent. So, for concerned parties of both groups... There is no intention, plan. idea, con- cept or anything of the kind to cease publi- cation of THE RAINBOW. I don't know how these rumors get started. I've heard them for a decade. Yes, we depend on advertis- ing revenue for the vast majority of our income and if advertising drops, so will the number of our pages. But if advertising revenues increase, our number of pages will also increase. There are a number of ways in which you can help. One way is to support our advertisers. Even if you are not familiar with their product, try something new. Another way you can help is to subscribe to THE RAINBOW. It is very expensive to make our magazine available for single-copy sales. We are curtailing sales locations because there is actually a loss taken on every magazine sold. It is also less expensive to receive the magazine through subscription than to pay for each individual copy. Many of you in the CoCo Community have been, and will continue to be, with us for a long time. One of the greatest mis- takes made by the old 80 Micro magazine was to abandon its Model I and Model III readers. There are no such plans for the CoCo Community. We cancelled our plans to publish the CoCo history book because the authors said that given their time constraints they would be unable to deliver it. We want to publish that book. We tried to find some- one who would write it for us. And when there was no other answer we refunded the money to those with pre-paid orders. We would still publish the book if an author is found. If you want to write it, please give me a call. We absolutely plan to have RAJNBOwfest in Chicago this spring. We have tried to encourage plans for one or two smaller fests this fall. These smaller fests will proba- bly not be as successful as RAlNBOWfest and participants should not be discouraged if they are not. We put a lot of punch behind our show. And, at least at this time, we feel it is better to have one big show per year than two. We have every intention to continue our support of both Disk basic and OS-9. We believe both systems offer many educa- tional opportunities. We will leave it up to you to choose whether or not to learn OS-9. You should understand that as a matter of policy (my personal policy) we will not support any other publication aimed at the CoCo Community. This is not a decision based on competition, it is a decision based on the difficulty of producing a magazine/ newsletter publication. Over the years there have been perhaps a dozen such publica- tions. They have all gone out of business and left a bad taste in the mouths of many people. Some of the competition has been very large and well-funded. And some of them closed their doors at the very height of CoCo sales. Each closing hurt our Commu- nity. I decided many years ago to never allow that to happen again. I am personally optimistic about the Color Computer and the CoCo Commu- nity. There are things that can be done on a CoCo today that could not be done on a mainframe when the CoCo was introduced. To have that much user-friendliness, power and potential means your CoCo will be useful for many years to come. And we intend to be part of that with you.

Those videos wiih titles and credits on hand lettered cards. Well, put away your markers, cardboard and rulers. Use the CoCo 3 to give your home videos a more polished look. With the right software and a few dollars worth of acces- sories, yours can be a professional creation with impressive titles, special effects and even some simple animation that can be added to your videos without expensive editing equipment. Composite Video: The Link to Your VCR or Camcorder If you look at the back of a vcr you will notice several jacks, including two marked Video In and Video Out. These jacks are used to make a direct connection to another video accessory, such as a monitor or another vcr. The signal is called composite, or baseband, video and contains the picture information to be displayed or recorded in a fomiat known as NTSC (National Televi- sion Standards Committee). The informa- Mark Haverstock and Bill Wills are ama- teur videophiles who hope to be successful on America's Funniest Home Videos.

Their usernames are DRDEBUG and basickid respective!) December 1990 THE RAINBOW 11 audio in video in t Figure 1: Typical VCR Hookup tion can be transferred directly and does not need to be tuned to a television receiver. When plugging a composite video source into a VCR, you can directly record that source. If you look on the back panel of the CoCo 3, you will see two small jacks la- beled Audio and Video. These jacks are very similar to those found on the VCR. The CoCo 3 has a composite video output that can be displayed on a monitor or recorded on a vcr. The CoCo 3 is a great choice for video titling. The RGB output can be hooked to the computer's monitor for previewing. The video output connects directly to the vcr*s video input for recording as shown in Fig- ure 1. Finally, the CoCo 3 can produce up to 16 colors at one time. Working With Video The CoCo 3 has two video outputs, RGB and composite. These are quite different, so what is seen on the computer's monitor will not necessarily appear the same way on a composite monitor. What you see isn't always what you get. Color and text will differ in tint and clarity. We suggest you watch the image of your final creation on a television connected to the VCR. Your pictures, titles, credits and anima- tion will be incorporated into your video through separate scenes dubbed to your home video. These are strictly stand-alone sequences suitable for beginnings, end- ings, intermissions and the like. They will not overlay existing video footage. In other words, you can't blend the graphics titles with pictures that already exist on your videotape. This would require expensive additional Genlock hardware. Rather than record the graphics titles over the original video tape, we recom- mend you dub the works to a second video recorder. This prevents accidental erasures on the original tape and provides some flexibility in editing your final production. You can easily remove mistakes and poorly shot scenes fora more polished production. A typical hookup diagram is shown in Figure 2. It consists of a CoCo 3, a video switchbox or special effects generator, a playback vcr, a record vcr and a TV. If available, a camcorder can be used as the record vcr. Camcorders usually have multiple record heads and sophisticated editing features that may prove beneficial to the overall outcome of your video. An optional video enhanceroramplifiercan be included to further improve the quality of your final copy. Audio mixers will blend narration and music for a pleasing effect. The original footage runs on the playback vcr. Graphics and titles are generated on the computer. You can switch back and forth between the two to create a desired product to send to the record VCR. You can build a video switchbox for about $5 with parts from your local Radio Shack, or the Radio Shack Audio/Video Control Center (Cat. #15-1956) is a ready- made unit that will work equally well. If additional editing features are needed, the Video Special Effects Switcher (Cat. #15- 1274) can handle fades, wipes and audio mixing. j^j^.

If you have to reach behind your VCR to plug and unplug cables when dubbing, you will appreciate the added convenience of having this switchbox. Switchbox assembly is simple and re- quires only a few tools. You will need a drill. 'A-inch drill bit, screwdriver, flat metal file, wire strippers, pliers, soldering iron and solder. You will also need a metal project box (Cat. #270-239), six phono jacks (Cat. #274- 346), a DPDT toggle switch (Cat. #275-636), wire, and dry-transfer lettering, all of which are available from Radio Shack. - . * > COWUI1 ii <4R n aviiai ■ • ■- ••" ■ t • Construction First, remove the cover of the box and the four screws packaged inside. Mark the positions of the holes to be drilled in the top and sides (see Figure 3). Then mark the positions of the holes on the back of the box. Drill all holes using the '/ 4-inch drill bit. Use the file to remove any burrs from inside the box. Apply the dry transfer lettering or the optional template to the top of the box. Label the audio and video jacks. Mount the switch in the hole on the top of the box. Remove the grounding tabs from the phono jacks. Mount each jack in the re- maining holes in the back and sides of the box. Be sure to tightly secure the nuts on each so they form a good connection to ground. Prepare six 3-inch pieces of wire by removing about '/i-inch of insulation from each end. Wire the audio/video output lines from the two middle terminals on the switch to the jacks on the back of the box (see Figure 4). Wire the remaining audio/video inputs to the switch as shown in Figure 4. Solder each connection carefully. Be sure to in- spect the solder connections for shorts. Test your box by plugging in your com- puter and vcr as described. If necessary. re-adjust the position of the switch to match the marked switch positions. Finally, re-assemble the box by care- fully tucking the wires inside. As a finish- ing touch, cover the dry transfer letters with clear nail polish to prevent them from rubbing off. Now you can enjoy the convenience of an audio/video switch for much less than commercially made units.

A common example of scrolling is the list of credits usually seen at the end of a movie. The new text appears on the bottom of the screen, works its way up and finally disappears at the top. Horizontal scrolling is also referred to as crawl. Animation Animation is the process of making an object appear to move on the screen. Computer animation is accomplished by drawing, erasing and then re-drawing text or pictures with little or no pause time in between. Transitions Transitions help to smoothly blend one graphic element of your script into another without the abrupt change from one scene to another. Some of the more common transitions are listed and ex- plained below. Fade In A fade in starts with a blank screen and slowly builds to show the complete scene. The effect is similar to standing in a dark room and slowly turning up the dimmer switch to full intensity. Fade Out The fade out is the opposite of the fade in. The picture starts at full intensity and gradually fades to a blank screen. Wipe A wipe partem begins by blocking out part of the existing picture and then slowly replaces it with the next picture. Visually a wipe is much like pulling down a window shade and revealing a new image. Wipes are usually from right to left, or from top to bottom on the screen. Cut The cut is an instantaneous transition from one shot to another without the gradual change. A common example of the cut is switching between the images of two people filmed during a phone conversation. Genlock Genlock is a hardware device that allows you to superimpose graphics or titles over an existing video picture. organize your pictures. The pictures can be cued one at a time with movement from one to the other by using the spacebar. An optional automatic wipe feature provides smooth transitions from one picture to the next should you decide to use them. The sample screens on RAINBOW ON DISK were created by Bill Wills with CoCoMaxlll and are visible when loaded into CoCo Show. CoCo Show is provided on this month's rainbow ON disk (courtesy of Colorware) so you can see examples of animated title screens. Although we recommend you use CoCo Max 111. other drawing programs for the CoCo can produce full-screen graphics suitable for video work. Examples of these programs include Color Max. The Rat and DeskMate. These programs' features may vary, but all can help create artwork or import pictures from clip-art disks to create your title screens. Editing Hints Tape editing can be a time consuming process. The object is to blend titles, spe- cial effects and pictures into an interesling and visually pleasing production with mini- mal blank spots and jumping in the final copy. Here are some hints designed to help make the editing experience a smooth one. First load a new blank videotape into your record vcr and set it to record at its highest speed, which is SP on VHS record- ers. Prepare the record VCR by simultane- ously pressing the record and pause but- tons. Use the pause button to stop and start the record vcr to minimize glitches in the final copy. Cue your videotape on the playback VCR and start a few seconds ahead of the scene you want to record. When the proper scene appears release the pause on the record machine. Press pause again after the scene. That's all there is to it. The pause can be left on for up to five minutes on most vcrs before it automatically returns to the stop mode. This should give you enough time to cue the next scene or a title screen. Switch between the computer and playback vcr when the recording vcr is paused. If you switch while recording, a glitch will appear in the tape. But. with a video special effects switcher you can wipe or fade between either input while the tape is still running. Be sure to preview your computer's video sequences before you record them. Sometimes a stopwatch is helpful when recording the running times. As we mentioned earlier, dubbing to a second VCR or camcorder is the easiest way to edit. The finished copy becomes a sec- ond generation copy of the original video and will not be quite as clear as the first. For this reason you may want to consider a signal amplifier or video enhancer to im- prove the quality of your final copy. Sometimes you may have access to only one VCR or camcorder or you just want to add titles to the original tape. If you must add titles to the original copy of the video, many of the newer VCRs have a feature (variously called Video Dub, Edit or Insert) that allows you to re-record a section of video on top of a previously recorded sec- tion. This is the mode to use when adding title sequences or graphics to your vide- otapes. The operation of these features will vary, so consult your owner's manual for more information. Older Color Computers If you have a CoCo 1 or 2 with a color composite video adapter, you can still gen- erate titles with CoCo Max, CoCo Max II and other graphics programs. The connec- tion will be the same as for the CoCo 3. Your capabilities will be somewhat limited based on the graphics program you use. The last and probably least desirable alternative is to tape the video directly from the computer monitor or TV. Although this process will produce an acceptable picture in most cases, it may contain an annoying flicker due to timing differences between the camcorder and the monitor. Summary The composite video output of your CoCo 3 provides the necessary link to your VCR with the capability to add titles, simple animation and video effects to your home videos. With the right software, a few inex- pensive accessories and some skillful edit- ing more polished home videos are yours.

The object is to steer the worm around the screen and eat the food. When the worm eats, she grows longer and the game grows more difficult. The point is to create as long a worm as possible. I wrote Wormy to run as fast as pos- sible without resorting to assembly-lan- guage programming. In fact, at the most difficult levels the game is almost too fast to play. The listing is short enough to be entered in a reasonable length of time and has enough features to satisfy most users. It includes seven levels of difficulty, continuous score display, high score, sound effects and single-stroke restart. The high degree of speed was achieved through a number of programming tricks, many discussed in prior issues of THE RAINBOW. The main loop was placed near the beginning of the program and calls to subroutines were kept to a mini- mum. Arrays were used generously to avoid repetitive calculation of frequently used values. The animation was acceler- ated by using pokes to text screen ad- dresses rather than PRINT @ statements. Variables were substituted for often-used floating-point numbers since these seem to run faster. Complicated floating-point calculations were avoided wherever possible. And finally. BASIC statements were combined to further expedite pro- gram execution. Enter the program exactly as shown in the listing and save a copy before running it. The few spaces that remain should not be deleted or the program will not run properly. The REM statements can be left out. If you have only 16K of RAM you will need to enter PCLEAR1 before loading the program or you'll get an out of memory error when the large array, A(999), is dimensioned. When run. Wormy shows you brief instructions on how to play. Choose your own level of difficulty. I recommend using Level 6 or 7 until you are comfort- able at higher levels. The G and H keys move the worm left and right, respec- tively. The E and F keys move it up and down. If you hit the edge of the screen or hit yourself, the game ends. The worm moves quickly, so keep your fingers placed lightly on these four keys at all times. As you play, you'll notice some inter- esting features. The length of your worm and the high score from your previous games are displayed at the top of the screen. The level of difficulty is shown in the lower-left corner of the screen. An undocumented use of the PLAY command has been used to produce the worm's voice (see lines 400-440). Note that as the worm grows, its voice gets deeper and more robust. You may pause the game by pressing SHIFT-®. This seemingly simple game actually requires some fairly sophisticated strat- egy since the path taken to the next bite of food determines the pattern of later ob- stacles. For really high scores, you must learn to make two consecutive right or left turns that cause the worm to double back. While it's theoretically possible to fill the entire screen with the worm's body, to increase speed I have not included code to actually test for this condition. If you somehow achieve this state (length of the worm = 390) the program goes into an infinite loop at Line 1 10 since there will be no unused space to place the next bite of food. Consider this as winning. The Listing: WORMY 'COPYRIGHT 1990 FALSOFT, INC. 10 ' WORMY DAN TANDBERG. M.D. ALBUQUERQUE.

So let's take another look at the C com- piler package originally sold to run under OS-9 Level I. Perhaps you can be encouraged to take that dusty package off the shelf and break new ground. We'll start by setting up the system. The disks shipped with Microware C for the Color Computer are very full. In fact there are only 109 free sectors remaining on the C Compiler disk and 199 on the C Library disk. This presented problems when the package was released in 1985 and most OS-9 users struggled with 35-track, single- sided disks. Now with the availability of many hard disk and RAM disk systems and the added versatility of OS-9 Level II run- ning on a 5I2K CoCo 3. most people find C much easier to tackle today than it was just five short years ago. If you are still struggling with an older disk system, here's a tip that may help you. It is sometimes easier to create several system disks: one for writing and testing assembly language programs, one for BAS- IC09 programs and another for C language programming sessions. There are two ways to make multiple system disks. You can use cobbler or os9gen to put the os9boot file on each of your system disks. Ifyoudothisyou will be able to boot os-9 with the disk containing the programs you need for the particular task at hand. Dale L. Puckeit. a freelance writer and programmer, sen'es as director-at-large of the OS-9 Users Group anil is a member of the Computer Press Association. His user- name on Delphi is DALEP: on packet-radio, KOHYD @ N4QQ; on GEnie, D.PUCKETT2; and on CIS. 71446.736. If you would rather not invest the time to create a new os9boot file on half a dozen disks and use dsave to move the required programs to each CMDS directory, simply maintain one system disk and a number of system programming disks. When you take this route, you will need to boot OS-9 with your single system disk and then swap disks to insert the system programming disk with the programs you need for the language you plan to use. Don't skip this step: After inserting the system programming disk use the chx command to make the CMDS directory on that disk your current execution directory. In other words after you remove your boot disk and insert your C programming disk you must enter the following: chx /dO/cmds This command tells OS-9 where to look for the utilities and programs you will be run- ning. We're assuming you have used the makdi r command to create the CMDS direc- tory on your C programming disk. You will need to create a CMDS directory on all sys- tem programming disks. After you create the CMDS directories, store the required executable object code files (the commands) in each new directory. Each CMDS directory will be different. For example, you'll need a different set of utility programs for word processing or BAS1C09 programming than for C programming. Since the CMOS directory on the C Compiler disk from Radio Shack uses all but i()9 sectors on the disk, use a backup copy of this disk as your programming disk C. You can use those 109 sectors to store a few additional tools to make programming easier. For example, you'll need to copy your favorite editor into the CMDS directory on this disk. You may also find a few compare and word-search utilities such as comm, dlff and grep useful. You can use the copy command to move a few utilities intoyournew CMDS directory. If you're copying a number of utilities into this directory, the dsave utility will be easier. Don't forget the golden rule of com- puter operation: Do not make these changes on your original C Compiler disk from Radio Shack. Instead, immediately put a write protect tab on that valuable disk. Then make a copy of it using backup. Put your original C Compiler disk away to make a new copy should something happen to your working disk. So far we have taken care of the C programming disk you will use in /dO. Now. we'll look at the disk needed for Drive 1 . It's a fact of life that to program in C using Color Computer OS-9, two disk drives are needed. For large programs, three drives are needed if you use the single- sided. 35-track drives first released for the Color Computer. But if you use 40- or 80- Irack. double-sided disk drives, two drives are sufficient. When you purchased Microware's C Compiler from Radio Shack you received two disks. The second disk is called the C Library. It contains three directories: DEFS. LIBS and SOURCES. TheCCompilerexpects to find the DEFS and LIBS directories on a disk mounted in /dl. If they arc not found there, the compiler will not work. The paths to the DEFS and LIBS directo- ries are hard coded in the C compiler to point to /dl. If you own a hard drive, or even a double-sided drive, you will want to patch your compiler so it looks for these directories on the default drive (/dd). The DEFS directory contains a file called 0S9defs.a. which stores the definitions needed by c.asm, the relocatable macro assembler included in the C Compiler package. Take a look at any of the assembly language source files in the SOURCES direc- December1990 THE RAINBOW 21 f=" tory. They are the ones with ihe . a exten- sion. YoiTll find most of them contain Ihe line: USE /defs/os9defs.a Essentially this tells the assembler to insert the source code stored in a file named os9defs.a. located in a directory named DEFS. Again. Ihe assumption is that the DEFS directory is on Ihe same drive as Ihe SOURCES directory, /dl. When Ihe assem- bler reads this file, it learns the symbolic names of the many OS-9 function calls and variables. On closer examination of the DEFS di- rectory on the C Library disk you'll find a numberof files with an . h extension. These are C header files. Header files usually contain collections of //define statements or declaralions and are read by the compi ler when you use an //include statement in your program. With (/Include stalements in your large programs you can guarantee thai all Ihe source files will use the same definitions and variable declaralions. Remember that if you change a header file you must reconstruct all files thai use it. For example, if you need ihe definitions that deal with OS-9 signals you must include this line in your program source code. //include <signal .h> The left and right angle brackets tell the C compiler to look for a file named s 1 gna 1 . h in the DEFS directory. If you have stored header files in other directories you can tell OS-9 where they are located by including a complete paihlisi to the file enclosed in double quotes. For example: //include "/dd/ALTDEFS/signal .h" Since the stdi o . h file will be needed with almost every C program you write, you'll need the DEFS directory on the disk in /dl. unless you've modified your compiler to use the default drive /dd. As your C pro- gramming career begins, you probably won't use the other files in the D E F S directory very often. Bui. leave ihem intact. You'll need them when you compile programs from other sources such as the OS-9 Users Group Software Library or RAINBOW ON DISK. The L I B directory contains a file named cl ib. 1 . which stores the standard library functions, math functions and other object code needed by Ihe system. Another file in thai directory is named cstart.r and con- tains code needed in all compiled pro- grams. It must be in ihe LIB directory and thai directory must be in a disk mounted in Drive /dl. or /dd if you've modified the compiler. The SOURCES directory holds the source code for three useful sample programs and adirectory named SYS that holds Ihe assem- bly language source code used to generate portions of Ihe object code in the clib.l 1 L ▼ J 1 ost people find C much easier to tackle today than it was just five short years ago. file. Studying these files will help you understand how the C Compiler works. If you are working with Ihe Radio Shack 35-track. single-sided drives, you should delete the SYS directory from the SOURCES directory to create more space for your own source code. You can also delete the sample C source code. Jusl remember to delete these files from your backup copy of the C library disk and not the original disk from Radio Shack. There were 199 free sectors available on the C Library disk before you deleted Ihe SYS directory, so you should have plenty of room. While learning this new language don'l forget the basics. Remember, the C com- piler will look for your source code and data files in your current data directory. The SOURCES directory would be a good starling place. Don't forget to use the end command before you start compiling your C programs. To do this, type: chd /dl/sources Now that you have set up your two disks dhe C Compiler for Drive /dO and Ihe C Library for Drive /dl) you are ready to begin programming. Use your favorite editor to create a file containing a short program. For example you could use this model from page six of Kemighan and Ritchie's The C Programming Language. main( ) ( printfChello. world\n"); 1 After you type this short program, save il in a file named hel 1 o . c. You're almost ready to compile your first C program. First make sure your C Compiler disk is in /dO and your current execution directory is /dO/ CHDS. Also, make sure your C Library disk is in /dl and your current data directory is /dl/SOURCES. Then, enter the command: ecl hello. c When you press enter, your disk drives will begin lo spin and after several minutes you'll see something like this on your screen: ■hello. c - c.prep: c.passl: c.passZ: c.opt: c.asm: cl ink: The name of the source file you are compil- ing is hel 1 o . c. The other lines tell which pan of the C Compiler is running. You'll notice thai /dO starts spinning each time a new line appears on the screen. Il is loading the next program into memory. Look in yourcurrent data directory after you compile Ihe above program to see a file named c . com. List il to leam why the above messages appeared on your screen. You'll also see what OS-9 did throughout the compiling process. Let's look: echo 'hello. c* -x echo c.prep: C.PREP hello. c >ctmp.4.m x echo c.passl: C.PASS1 ctmp.4.m -o-ctmp.4.1 del ctmp.4.m echo c.pass2: C.PASS2 ctmp.4.i -o-ctmp.4.a del ctmp.4.i echo c.opt: C.OPT ctmp.4.a ctmp.4.o del ctmp.4.a echo c.asm: C.ASM ctmp.4.o. -0-ctmp.4.r del ctmp.4.o echo clink: CLINK /dl/lib/cstart.r ctmp.4.r -o-hello -Wdl/lib/clib.l del ctmp.r Let's study this listing, c.com is an OS-9 procedure file generated by ccl. It puts the various parts of the C compiler through its paces. The first line in this procedure file tells 22 THE RAINBOW December 1990 OS-9 10 echo the name of the file being compiled. It then sends the built-in Shell command, -x. This tells the Shell not to abort the process if an error occurs. After sending this signal the procedure file echoes c.prep: on your screen letting you know the name of the program it plans to run next. It then sends the command to run c.prep. The same line tells c.prep to get its input from the file named hel 1 o . c in your current data directory and to put its output into an intermediate file named ctmp.4.m. When c.prep completes its job. the procedure file sends an x command to the Shell. This tells the Shell to abort if there is an error. It then echoes c . pa s s 1 : and pro- ceeds to run that program. Notice that c. pas si gets its input from the file named ctmp.4.m that was just cre- ated by c . prep, c . pass 1 sends its output to a file named ctmp.4.1. As you study the rest of the c . com pro- cedure file a pattern will become obvious. os-9 is using a series of temporary files to store intermediate results. The output of one part of the compiler is put into a tempo- rary file used as the input for the next part of the compiler. After the temporary files have been used, they are deleted. ^include <t1me.h> struct sgtbuf buf: /* Your "main ()" program goes here */ get1me(Sbuf ) : pr1ntf(-X02d/X02d/%02d *02d:X02d:X02d\n".buf .tjnonth. buf.t_d ay. buf.t_year. buf.t_hour. buf .t_minute. buf .t_second): Figure 1: Clock Program These temporary files act like a pipe. The difference is the compiler is so large that it won't all fit in memory at once. The temporary files are needed to hold the re- sults from one part of the compiler while the next pan is loaded into memory. This was the only way to make the compiler work on the older Level I systems. Work your way through the procedure file one line at a time until you understand what happens during each part of the compilation. Notice that several compiler parts can be used as stand-alone programs. For example you can use the relocatable macro assembler (c.asm) io create an as- sembly language source file that you have written. When you write in the C language the compiler writes an assembly-language source-code file for you. When you get to the command for c . 1 i n k . the linker program, it will be obvious why you must have a directory named L I B on a disk mounted in /dl. The linker reads two files from this directory, cstart.r and cllb.l. We haven't jumped into the mystery of C programming in this short tutorial, but hopefully we have helped you understand how to set up your Color Computer OS-9 system to effectively use the Microware C compiler.

The code in Figure I should do the job. When your program runs this code it should print the lime in the standard mm/ dd/yy hh:mm:ss format. The X02d's in the code above tell prl ntf you want the infor- mation printed in decimal. You always want it printed as two digits with a leading zero as a pad if necessary. In other words New Year' s Day will come out as o i /u I /9 1 . not 1/1/91. One more note about C. Many people say they don't like C because the code it generates is too long. Before you jump to this conclusion, consider this: You can't really compare the size of a finished C program to a BASIC09 program unless you play fairly and count the size of BASlC09's runD module. Remember that runb must be in mem- ory if you are going to run your packed BASIC09 programs directly from your exe- cution directory. When this factor is added you realize that C programs are really shorter than b AS1C09 programs since the standard C library stored in cllb.1 is shorter than runb. If you're fortunate enough toown a 51 2K CoCo 3 running OS-9 Level It, you can really speed up the C compiler by making a quick patch to the ccl file and preloading the modules used by the C compiler. In the ccl file the string /dl is located at an offset of S0EE4 from the beginning of the module. In hexadecimal this string reads 2F6431. Using tnodpatch or debug, change the 31 to M and save a new copy of cc 1 . This forces the linker to look for the LIB directory on Drive /dd (yourhard drive or high-capacity floppy). To preload the compiler, use build to create the following procedure file: load ccl load c.prep load c.passl load c.pass2 load c.opt load c.asm load clink With 5I2K you should be able to load most, if not all. the C compiler modules into memory. This step, along with the patch above, will cut your compiling time to less than a minute. You can speed com- pilation even further by putting your source code in a ram disk and changing your current data directory to the RAM disk. This will cause the compiler to write its tempo- rary files to the RAM disk. Disto Delivers a Megabyte of Memory Once again Tony DiStefano has teamed up with Chris and Joanne Rochon at CRC to deliver another landmark OS-9 solution. Thanks to Tony's genius and Kevin Dar- ling's programming prowess, you can now equip your CoCo 3 with one megabyte of memory. The Disto kit adds to the page switching capability in your CoCos gime so that it can access the entire megabyte of memory. I recently installed the kit and was astounded with my first free memory re- port. After loading DynaSlar and BAS1C09 and several sets of utilities. I entered mfree. The program reported 864K of available memory. Installation in my CoCo 3 was particu- larly easy since I had previously installed the 68(» microprocessor in a socket. Disto's kit adds two small internal boards to your CoCo. The first has 512K and is equipped with sockets that let you plug the original 5I2K on lop of it. The second board holds the page switching circuit that lets the GIME recognize the extra memory. This second board must be soldered to all 40 pins of the 6809. Operation of the CoCo 3 with a full megabyte of memory is a whole new expe- rience. You can almost preload every OS-9 program you own into memory and have it available within a split second. It's also a real gift for C programmers since it lets them preload all of the C compiler modules in memory with enough space left over to create a small RAM disk to store and read the many temporary files created by the com- piler. These two steps can cut your compile lime to a fourth of its original. For a detailed technical review of the Disto One Megabyte add-on kit. see the excellent review by Greg Law in the August 1990 issue of THE RAINBOW. A Multi-Vue Word Processing Shell Zack Sessions is a CoCo developer who has jumped on the Multi-Vue bandwagon. Zack can be contacted through Colorsys- tems. Box 540, Castle Hayne. NC 28429. WPSliell is a word processing-oriented graph- ics Shell that delivers a point and click interface with pull-down menus to do your word processing chores. It is similar in appearance to Mulii-Vue's gshell and MVCanvas from HyperTech. Essentially it brings all major word processing tasks together under one Shell. You supply your favorite text editor, text formatter and spell- ing checker programs, wpshell integrates them into one package. WPSliell Is a bargain at S22. It requires the wi ndi nt module from your Radio Shack Multi-Vue disk. With wpshell, you can combine an ex- isting public domain text editor, text for- matter, spelling checker and a more utility to build a full powered word processing system. It also makes these tools available with a click or two of your mouse button. It was written in 6809 assembly language using the RMA assembler. The more utility is a staple from the UNIX world that displays the contents of a file to the standard output path one screen at a time. It then waits for further instruction from you on whether to display the next screen, back up or skip forward. Sessions recommends Pete Lyall's excellent OS-9 port of the UNIX standard. wpshell is easily installed. Simply copy the program to the /dd/CMDS directory and copy the wpenv .file to your /dd/SYS di- rectory. Once these files have been copied, edit the environment file (wpenv. file) to match your system. Free Ham/os-9 BBS Online The Thermal Fusion BBS in Greenville. SC, is now online and available. It is dedi- cated to all owners of CoCo 2s and 3s and is of special interest to amateur radio opera- tors as well as OS-9 users. To connect, call 803-862-7544 at any speed between 300 and 9600 bps. Use eight bits with no parity and one stop bit. Unlimited shareware uploads and down- loads are permitted. You'll find many OS-9 programs and many BASIC games and utili- ties. Amateur radio operators will find radioteletype and slow-scan television software as well as satellite-tracking pro- grams. Of special interest to hams is the WJ5W CoCo Packet Radio Bulletin Board, Version 4.02. Monty W. Haley wrote the BBS program and normally distributes it with his CoCo Packet Radio Terminal program (CoCoPACT). Although CoCoPACT is not an OS-9 program, you can buy it directly from Haley at Route 1. Box 210-B, Evening Shade. AR 72532. Another amateur packet radio program is CoCoPacket. avail- able from Brian Carling at 5131 Ray wood Lane. Nashville, TN 37211. Thanks to Skip Mehlenbacher, W8HFA. for the tip. While we're on the subject of amateur radio, thanks to James Jones of Microware for my copy of the object and source code for the public domain KA9Q TCP/IP OSK network program. It's an earlier version dated from late 1986. Any amateur who needs this code as a staning point for a conversion to OS-9 for the CoCo may con- tact me at kohyd@wfoa. Incidentally, my IP address is [44.122.0.4]. That wraps up another year of Kissable OS-9. Have a happy holiday season and an outstanding new year.

Scerbo Contributing Editor If you have an idea for the "Wishing Well," submit it to Fred do the rain- bow. Remember, keep your ideas spe- cific, and don't forget this is basic. All programs resulting from your wishes- are for your use, but remain the prop- erty of the author. Last month we introduced the graph- ics needed to create an educa- tional program that reviewed the 50 states. This month those graph- ics are merged with a revised version of the Match Game that was intro- duced many months ago. I hope by now most of you have a working copy of The 50 States from last month. You may have noticed the article was short and the program listing was very long. The data statements required were rather complex since over one hundred were needed to create the graphics maps and titles for the 50 states. And that doesn't even include the additional data statements that create the title card or those that create the string locations for positioning the graphics. This month's listing is no exception. The data statements that create the maps and titles remain exactly the same as in last month's listing. I have even used the same line numbers for these data statements, so it is not necessary for you to retype the entire listing. Fred Scerbo is a special needs instructor for the North Adams Public Schools in North Adams. Massachusetts. He holds a master's in education and has published some of the first software available for the Color Computer through his software firm , Illustrated Memory Banks. Getting Started Load your working copy of The 50 States from last month into your CoCo. The lines to save are those between 1000 and 2490. Therefore, enter DEL -999 and DEL 2491 - to get rid of the old lines. his program is a good way to review material presented in The 50 States. Next, take this month's listing and enter all the remaining lines of the program. This will save you a considerable amount of time. You can also use these same commands to create last month's program from this month's listing. First, delete the extra lines after this month's listing has been typed and saved. Then enter the remaining lines from last month's program. So What's New? Earlier in this column I mentioned this is a revised version of our original Match Game. The program originally used the PCLEAR8 and PCOPY commands to increase the speed of the graphics. However we are now using a much larger graphics array to store these 50 states. Match Game origi- nally stored only 20 sets of opposites. As you can see, the number of graphics used has been more than doubled and we would very quickly run out of usable memory with these original commands. The PCLEAR8 command alone eats up four additional graphics pages of usable memory. There- fore, I went through the original listing and killed any references to PCLEAR. PCOPY and any graphics page higher than four. (Thus, PM0DE4 . 5 would be out of the question.) I quickly discovered my original use of the PCOPY command was unnecessary since this version seems to execute as quickly as the original. (This also means I can now make plans for larger uses of this shell since its storage capacity has more than doubled. Any ideas out there?) Using the Program You get our standard title card when you run this program. Since this version does not allow you to kill part of the graphics like the earlier version, you simply press ENTER to start the game. This game involves two players and is a standard Concentration-type game. Each player uncovers two squares at a time. Use the arrow keys to move the flashing cursor around the screen. When you reach a square you want to choose, press ENTER. When a match is made, it is recognized by the computer. To let the next player take a turn, press the Spacebar. When the game is over, the scorecard will indicate the winner. This program is a good way to review material presented in The 50 States. You really do not need last month's program to enjoy this one. By itself. The Match Game of 50 States can be fun for young and old alike. Let me know what you think. Conclusion I think by now many of our regular readers know how flexible these various shell programs can be.

Unfortunately these methods are complex and BASIC09 programs to decode them would be long and slow-running. Because of this, the second part of this article addresses some changes and im- provements to our VEF program. The com- pression methods discussed are those used by CM3 and GIF formats. They are a little tough to understand, so if you have diffi- culty, go to the second half and find out about the improvements made to the VEF viewer. Non-RLE Compression Last month several different variants of a compression method known as Run- Length Encoding (RLE) were discussed. This method is so named since it com- Tim Kientzle is currently pursuing a doc- torate in mathematics at the University of California at Berkeley and has worked with the CoCo since 1982. He is best known in the CoCo world as the author ofV-Term. He can be found on Delphi as TIMKIENTZLE. Or you can contact him at 14 Croxton Avenue, Oakland, CA 94611. Another look at data- compression techniques presses files by encoding sequences of a single repeated byte, or run. Due to its simplicity, variations of RLE are very common. There are. of course, other meth- ods. CoCo Max III has an interesting and effective compression method that encodes repeated bytes occurring either horizon- tally or vertically. By taking advantage of vertical and horizontal repetition, it can compress many graphics files significantly better than most of the RLE variants. The CompuServe Information Service (CIS) has standardized its Graphics Interchange For- mat (GIF) to allow many different types of computers to share picture files. This is done by storing detailed information about picture resolution and color mapping so that viewer programs can adapt the picture to whatever display hardware is available. GIF is also somewhat remarkable since it uses a sophisticated compression method known as Lempel-Ziv- Welch compression (LZW), so named after its three founders. LZW creates a table of common sequences of bytes and uses this table to encode the data. Since this method automatically adapts to any kind of data by generating this table from the specific data file, it is very effec- tive at compressing many kinds of data. Vertical and Horizontal Compression CM3 format does several things to sim- plify programming, provide good compres- sion and to avoid lengthening files. These will be discussed without much detail. CM3 compresses each line separately. Each line of the graphics data is stored with a header byte followed by the graphics data. This helps to simplify programming since each line can be handled separately. It also helps prevent the lengthening of files. If a line would be too long compressed, it can be stored uncompressed. This means that in the worst case only one byte would be added for each graphics line. The compres- sion uses two arrays of bits that tell how to restore each byte on the line. A compressed line starts with an array of 160 bits (20 34 THE RAINBOW December 1990 bytes), one bit for each byte of graphics data on this line. If the corresponding bit is zero, the previous byte is duplicated. If the bit is one. a bit is checked in a second array. If that bit is zero, the byte above is dupli- cated. Otherwise, a byte is copied from the data stored in this line. This requires only one bit if a byte duplicates the one before it, two bits if the the byte duplicates the one above it or 10 bits if the byte doesn't satisfy either of these. As long as there are a lot of bytes that are either horizontally or verti- cally duplicated, this will work well. But even if there aren't the line can always be stored uncompressed. For many files this might mean lines in the middle of a picture (where there is probably more detail) might be stored uncompressed, while lines at the top and bottom would be stored compressed. Storing Patterns The Lempel-Ziv-Welch compression method used by GIF is rapidly becoming an industry standard. The OS-9 archiving programs ar and pak use it, as do the MS- DOS programs ARC and ZOO, the Unix com- press program and others. The method was originally described by the authors in a series of articles published in professional magazines. The full details of lzw com- pression can get complicated, but the basic idea is simple. The ideas behind lzw compression are described first, then we'll take a look at some other features of the GIF format. If you think about it, the only way files can be compressed is to take advantage of repeated patterns in the data. For RLE, the kind of pattern exploited is a repeated single byte. For CM3, the patterns looked for are single bytes repeated either vertically or horizontally. In the case of LZW compres- sion, the patterns compressed are deter- mined from the data itself. An LZW encoder keeps a table of each sequence of bytes it sees, then uses the position in that table as a code for that sequence. As a rough ex- ample, if it read abcdabc it would first store the sequence ab, then the sequence cd. Next it would see ab, encode that using the code for ab and then store abc in the table. Each time it sees a sequence that extends an already known sequence, that sequence is added to the table. In this way it can adapt to almost any sort of data. The only tricky part of this is that the encoder must make sure the decoder can figure out this mess. Citing from the above example, if we put ab in our table and then immediately used that code, the decoder would not know what the code stood for. Instead, the encoder will simply not use a code that has just been added to the table. This way the decoder can build its own table of codes and be assured that whenever it sees a code in the data, that code is already in its own table of sequences. The strong point of GIF is its compres- sion method. This method fulfills one of the twodesign goals of the format, which is to reduce file size for quick transmission between systems. The other goal is to allow picture reproduction on any system. For this reason GIF is careful to store the picture size and color information in a format that is easily interpreted on a wide variety of computers. An obvious question to ask is that if GIF has such a great compression method, then why isn't it being used by everyone? There are two reasons for its lack of universal appeal. First of all, GIF is intended to allow picture files to be moved between many different types of computers. As a result it avoids storing information that might not be useful on some machines like animation information or pattern data. There is also a trade-off in complexity. GIF is much more complex than RLE approaches. GIF requires more data memory (the encode/decode tables require at least 16K), more program code and more time to encode or decode a file. For many program authors this is simply not worth the benefits. More Level II Tips and Tricks Let's think about ways to increase the speed of our vef program. If you look at the vef program, there are three major pieces of code. The first procedure reads and inter- prets the header. The second retrieves a 1 ine of graphics data from the file. The third procedure puts that line of graphics data on the screen. The header is read only once per picture and additional speed in this opera- tion would not significantly effect the speed of the program. When retrieving a line of graphics data from the file, there are few ways faster than a Get of the entire line, which is used for uncompressed data. Last month a trick was shown using an OS-9 system call to get exactly one compressed packet. The reason Get can't be used to retrieve the entire packet is that the length of the packet is not known in advance. Get always reads exactly enough to fill the appropriate variable. The only part left to improve upon is the code to put a line of graphics on the screen. You may recall in the first part of this t .

The first method was the one used in the PutLi ne procedure, the GPLoad escape sequence. This sequence causes the window system to store the following data into a Get/Put buffer, which can then be put directly on the screen. (This is the Put of a graphics image on the screen and not the BASIC09 PUT command to write a variable to a file.) The problem with this method is that OS-9 transfers the data from your program to the window system one byte at a time. It would be much faster to copy the data directly into the Get/Put buffer. An example of this can be seen in Listing 1 . It uses a GetStat call to map the buffer so it can be accessed directly. This is faster than the GPLoad sequence originally used. Don't spend a lot of time re-creating the buffer from scratch if it can be avoided. This process can be avoided with a new procedure to create and map-in the buffer, which is run near the beginning of VEF. To accommodate this, a few changes must be made to our main VEF procedure. These changes are included in the revised vef procedure in Listing 1. There is very little speed gained with this version since the PutLi ne routine has to copy the data byte-by-byte to the buffer. This process is just as slow as having the window system do it with GPLoad. To cor- rect this have the GetLine routine put the line data directly into the buffer, which makes it unnecessary for us to copy the line data around. An example of this is in List- ing 2. Since the required changes (remov- ing the Li ne variable and using a variable to hold the address of the Get/Put buffer) affect nearly every procedure, a full listing has been included. This version is almost as fast when displaying uncompressed VEF pictures as programs written completely in C or assembly language.

Project Ideas Once you understand the vef program and the changes made to it. there are several other programs to try. Change the final version of the VEF program to handle MGE format pictures. If you know C or assembly, rewrite the VEF program in either of these languages. At the very least, rewrite the UnSquash procedure. You might even try finding a good description of the CM3 format and writing a display program for that. Saving a graphics screen can be done in essentially the same way. The only differ- ence is that you use the GetBl k operation to get a line of graphics into a buffer, map in the buffer and then output the data. You will have to work around a minor bug that prevents the GetBl k operation from work- ing on the full width of the screen. (You'll have to get only '/z of the line at a time.) If you have access to information on other graphics formats, compare it to those discussed here. In particular, try to figure out how the compression method works and whether or not it would work better than any of these.

Boynton Very few people know much about the OS-9 F$Alarm (callcode $1E) system call due to its lack of documenta- tion by Tandy in the Techni- cal Reference section of the Level II man- ual. When I first learned to use syscall under BASIC09, 1 thought it would be neat to set an alarm. -So I gave it the address of a time packet and had no success. I then tried using the other registers, but still had no luck. After a while I completely forgot about it. Then one day I bought Inside OS- 9 Level ll from Frank Hogg Laboratories David P. Boynton is a sophomore at Sun- nyslope High School and has worked for two years in computer maintenance at a local newspaper. In his spare time David enjoys football, wrestling and computer programming. He can be contacted at SS27 N. 35th Dr., Phoenix. AR 85051.

END and read the "Bugs" section of the book. This section told me more about the alarm call. I began to experiment with this call and discovered its usefulness. The alarm call has four different func- tions. The call sets the alarm (actually the CC3I0 module) to make a tone once per second for a duration of 15 seconds. It also sets the alarm for cl ock to send a process signal on time match, gets the alarm status and clears the alarm. To tell the clock which function you want, set the A and B registers upon entry to the call. The entry conditions for the call are shown in Figure 1 . I have written a short BASIC09 procedure named Alarm to demonstrate the alarm's functions. This procedure was written as a command line utility and as such all input is given on the command line. It will not prompt you for anything except to clear the alarm. The command syntax is as follows: alarm <Function> [Date] [Time] [Procid] [Signal] The functions are: 1 — set audio alarm 2 — set signal alarm 3 — get alarm status 4 — clear alarm The date and time must be padded with zeros for the procedure to be read properly, syscall and in key must also be in memory or in the current execution directory. For example, if you want to set an audio alarm for August 8, 1990, at 5:30 p.m., enter: alarm 1 90/08/08 17:30 If you use the standard shel 1 supplied by Tandy, enclose ail the parameters in paren- thesis and quotes as follows: alarmC'l". "90/08/08". "17:30") Since I use ShellPlus, this is done for me. You can find ShellPlus on Delphi or just about any CoCo BBS. To get the status and clear the alarm, the only parameter is the proper function. For example, to get the status, enter al arm 3. I hope this was informative and you will find many uses for the call. Have fun with the program. <W» 44 THE RAINBOW December 1 990 TANDY SPECIAL OF THE MONTH DRIVE CARDS For model 1000. SX. TX. SL.

A *7777ZZZHZZZZ& dd-on is a word game plus a whole lot more. Il is simi- lar to a popular board game but has a few differences in scor- ing. To play this game you must have a CoCo 3 with a joystick or mouse plugged into the right joystick port. You can use a composite monitor. RGB monitor or a tele- vision set. Since this program uses the high Joel Mathew Hegherg has been program- ming for seven years. He enjoys creating games and utilities for the Color Com- puter. In his spare time he teaches others how to use computers. For further infor- mation on this program contact Joel at 936 N.ttth St.. Dekalb. IL 60115. resolution screen of the CoCo 3. an RGB monitor works best. I've also kept televi- sion users in mind by not using the first few columns of the screen since these cannot be seen when using a TV set. The object of Add-on is to create as many words as possible while gaining the most points. Points are awarded for each letter in the words you create. You only get points for the word that you create. For example, if you create the word "mob' (see Figure 1 ) you will have indirectly created the words 'not*, 'be' and 'farms.' You will only get points for the word 'mob.' Also on the grid are some colored squares. The dark red squares multiply the score of the word you create by three. The orange squares multiply the score by two. The dark blue squares multiply the score for the letter that occupies that square by three and the light blue squares multiply it by two. Words are created from the letters on the grid. To begin the game, the computer randomly selects a starting word. New words must originate from one of the words al- ready on the grid. To start a game, players must first select their tiles. These tiles are turned over to keep you from knowing the letters you have. Next, a grid appears on the screen and the first player's tiles are dis- played face up. That player should study both his letters and the words on the grid. When a word is chosen, the player enters it via the keyboard. Using the joystick/mouse, move the cursor to the square where your word should begin and click the button. Push the arrow key to show in which direc- tion the word should go (downward or to the right). If everything is done correctly, your word is placed on the grid. If you make a mistake typing your word and you've already entered it. simply press CLEAR to re-enter your word. If you cannot make a word, you may pass to the next player without receiving any points. To pass your turn, click the joystick/mouse when you would normally be entering your word. For the most part, any instructions needed are given onscreen. The * tile is a wild card letter. It isn't worth any points, but can be good to have. To create a word with this wild card, the player must include the * within the word. For example, you might eatetprin*er for the word printer. m . ....... ....... ...... ......... I I IF! I I •....4. ..<.....}... .<....{ i i IA; I ! IHiOiRiN; I i i IMIOIBI :p;A;S;T;E: -......•..,..■......'.....'.....■ Figure 1: Word Creation The game ends at playerdiscretion. This could be when you have run out of tiles or you cannot make any more words with your current letter tiles. If you are in a multi-player game, the rule for when a game ends should be mutually agreed upon prior to play. To end the game, press BREAK. At the beginning of this article I said "a word game plus a whole lot more." By this I mean the extensive point and click system used in this program. I designed this pro- 46 THE RAINBOW December 1990 gram to give the player more control over what happens in the game. When you first run the program, a blue screen appears with CMP on one side and RGB on the other. Simply point to the side for your monitor (television sets use CMP colors) and click the joystick/mouse but- ton. These are the default colors. You may change or edit these by clicking on the Colors menu selection. To change a color, simply point to the box containing the color and hold down the joystick/mouse button. Quickly clicking the button changes the colors one at a time. Clicking the word Border changes the border color. If you make a mistake and/or want the default colors, simply click on the word CMP or the word RGB. You can return to the main menu at any time by pressing break. Doing this in the middle of a game causes your final scores to be displayed until you click the joystick/ mouse button. To return to BASIC, simply click on the BASIC menu selection. Have fun and enjoy! Please feel free to contact me if you have any questions or comments about this program. Click on the About Add-on menu selection.

The dollar bill created by this program can be altered by changing the ASCII code for the border or the center. For example to change the dollar sign in the center to an asterisk, first find the ASCII code for the asterisk. Next type PRINT ASC("*") and press ENTER.

Turn of the Screw EPROM Programmer Handbook by Tony DiStefano Contributing Editor Data used to program an EPROM can be a customized DOS, a frequently used util- ity, or a fun game. In some cases a knowledge of ma- chine-language programming may be nec- essary. Whatever the data, it must be in memory before you load and execute the mprom software. The software expects the data to start at memory location 12288 (S3000). All numbers in Hex will be preceded by a $. In the case of a 2764 EPROM. the data ends at 20479 (S4FFF). For a 27128 chip, the end address is 28671 (S6FFF). In the case of the 27256. only half of the EPROM can be pro- grammed at a time. To program a 27256 you must program both halves individually and make sure you program the right data. In both cases the data start and end locations are the same as a 27128. After the data is loaded into memory, load the MPROM software by typing LOADM "MPROM": EXEC. You are greeted with the title page and the option to work with a 2764, a 27128 or one of two halves of a 27256 EPROM. Choose the proper EPROM and press ENTER. If the wrong EPROM is inserted into the socket, you will not damage the EPROM or the adapter, but it will not properly program or verify. The next screen to appear is the Main menu. Following is a detailed description of each item in this menu. 1. EPROM ERASED? — verifies the EPROM is completely erased. Initially and after each Tony DiStefano is a well-known early spe- cialist in computer hardware projects. He lives in Laval Onest. Quebec. Tony's user- name on Delphi is DISTO. erasure, all bits of the EPROM are in the logic 1 (High) state. The status line starts by printing CHECKING FOR FF's If all bits are erased the status line will indicate OK! at the end. If a location is not properly erased, the status line appears as AT XXXX EXPECTED FF FOUND YY XXXX is the EPROM address (starting from 0), FF is the expected data (in this case it is all ones or 255, SFF) and YY is the actual data found. If more than one address is not completely erased, the last non-erased address appears on the status line. When checking an EPROM to make sure it is erased, the OK must appear on the status line. If just one bit is missing, the EPROM is not fully erased and cannot be properly programmed. To erase a used eprom, use ultraviolet light. Refer to the EPROM eraser's manual for more details. 2 . PROGRAM EPROM — starts the program- ming process. This transfers the data in memory to the EPROM. Before starting this process, make sure the properly erased EPROM is placed in the socket. Pin 1 of the eprom goes to Pin 1 of the socket. Pin 1 of the socket is in the lower right corner when sitting in front of the keyboard with the MPROM and controller plugged into the computer. Make sure the battery pack is properly connected before starting. The process starts by displaying the following message on the status line PROGRAMMING ADDRESS: XXXX YY XXXX is the current EPROM address being programmed and YY is the program pulse width. Let me explain. In the good old days it was believed that each location of an eprom had to be programmed for about 50ms. or about '/m of a second. It doesn't sound like a lot of time, but when you have a 16K eprom, it takes over 14 minutes. Today's EPROMs do not have to be pro- grammed so long. Initially, a 1ms program pulse is sent to the address being pro- grammed. If it proves to be enough and the data is correct, a 4ms insurance pulse is given. If the verification shows invalid data, additional 1ms pulses are sent until the data is correct or the system has sent a maximum of 15 pulses. Then an insurance pulse four times greater than the number of pulses sent is given and the value of YY is changed to reflect the new pulse width. If the eprom data is still not valid, the pro- gram gives up and issues a status line of EPROM NOT PROGAMMED PROPERLY AT ADDRESS:XXXX XXXX is the address where the EPROM failed. At this point, re-program the EPROM. If it fails at the same address, there is a problem with the EPROM and it should not be used. If it fails at the next address, the batteries may be weak and need replacing. Caution: Never plug or unplug the battery pack with an EPROM in the socket. Always remove the EPROM first. When all the addresses of the EPROM are properly programmed, OK! is printed on the status line. 3. VERIFY EPROM — Even though EPROMs are verified during the programming stage, it is sometimes necessary to verify an EPROM without programming it, such as when comparing two EPROMs. The EPROM is verified by comparing the data found in the 52 THE RAINBOW December 1990 EPROM to that in memory. The status line reads VERIFYING EPROM If no difference is found, OK! is displayed on the status line. If a difference is found the status line changes to AT XXXX EXPECTED YY FOUND 11 xxxx is the address where the discrepancy was found, YY is the data it expected to find and ZZ is the actual data found. If more discrepancies are found, only the last one is shown on the screen. 4 . READ EPROM — It is sometimes neces- sary to transfer data from one EPROM to another or from an EPROM to disk. In either case data must first be transferred from EPROM to memory. This option transfers the contents of the EPROM into memory. The data resides in memory starting from 1 2288 (S3000) and is either 8K or 1 6K for a2764 and 27 1 28 respectively. Either half of a 27256 is 16K. The status line displays MOVING EPROM TO MEMORY and OK! is printed when the move is fin- ished. No verification is done when reading the EPROM. Verify the EPROM after a move with Option 3. 5. RETURN TO BASIC — When all EPROM activity is completed, this option returns you to BASIC. The MPROM software is still intact and you can return to it by entering EXEC (as long as you have not changed the execute address). The EPROM data is also intact. It is still in memory and unchanged. Now is the time to save the EPROM data to disk. For a 2674 the proper format for saving data is SAVEM "/7/e/iaw<?".&'H3000.&H4FFF.& HA027 filename is the standard filename, exten- tion and drive number. The next three val- ues are the start, end and execute addresses. The execute address has been chosen so that a warm start to BASIC will not crash into unwanted data. To save a 27128 or either half of a 27256 EPROM data, change the end address value from &H4FFF to &H6FFF. 6. EXAMINE/CHANGE MEMORY — used to change or verify existing data already loaded into memory. The status line prompts you for a start address. The address must be entered in Hex values only. When you are finished, press ENTER. The next line dis- played shows the address requested and the contents of that memory location. You have three choices. The first choice is to use the up or down arrows to increase or de- crease the address value by one. You can also enter a two digit Hex value that will automatically replace the old value. Or simply press ENTER and return to the Main menu. Hints & Tips A. Use these steps to make a copy of a DOS already in the controller on a CoCo I or 2. 1) Use the DOS command (or pokes) to switch to the desired DOS (DISTO Super Controller I only). Insure that the logo of the DOS you want copied is on the screen. 2) Save the DOS on disk: For an 8K DOS, enter SAVEM 7;/ena/w",&HC000.&HDFFF.& HA027 For a 16K DOS, enter SAVEM T?/6?jatfi? M .&HC000.&HFEFF.& HA027 3) With the MPROM adapter properly plugged in. reload the DOS with an offset: LOADM "filename" .W7 000 4) Load and execute the MPROM software. The offset used in Step 3 automatically puts that DOS at address 12288 (S3000). 5) Select the 2764 EPROM for an 8K DOS or the 27128 EPROM for a 16K DOS. 6) Insert the proper EPROM into the ZIF socket. 7) Insure the EPROM is blank by choosing Option 1 on the Main menu. 8) Program the EPROM with Option 2. 9) Verify that the EPROM is properly pro- grammed by selecting Option 3. 10) Remove the EPROM from the ZIF socket. Turn the computer off and insert the EPROM into your Disto controller. To burn eproms with disk-loaded DOSs, such as ADOS, follow the instructions sup- plied with the DOS on how to prepare it for EPROM. Then follow steps 2 through 10 above. Burning a new DOS with a CoCo 3 is somewhat different. The DOS does not operate from ROM as with the CoCo 1 and CoCo 2. Instead, the CoCo 3 software reads the DOS into RAM, then modifies and adds to it. You cannot use the above steps. You must remove the DOS from the controller, temporarily replace it with another DOS and read the DOS in the EPROM programmer. B. Some of the more experienced hardware buffs may want to fit a 2764 into a 24-pin socket. The following is a step-by-step procedure to do this. Soldering experience is required. 1) Move the two jumpers on the solder side of the MPROM board to cover the center pin and the other pin. This swaps ai i and AI2 for ihe 24-pin socket. 2) Program the 2764 as usual. 3) Bend Pin 2(> on the EPROM so it points up. Solder a short piece of wire from this pin to Pin 22. 4) Solder pins I, 26. 27 and 28 together. 5) Solder a piece of wire to Pin 2 of the eprom. Insert the other side of this wire into the socket hole left by Pin 20. 6) Inset the 2764 into the 24-pin socket. Pin 3 of the 2764 must go into Pin 1 of the socket. Pin 4 of the 2764 into Pin 2 of the socket, and so on. /R\ BED Binary Editor for Disk * BED will get rid of 99 percent of your disk problems.

Reader response was excellent with Keiran Kenny of Cremorne, NSW, Australia, winning the special long distance award. I'm always amazed by the programming proficiency and knowledge of CoCo users. I usually wind up learning more from readers' letters than I provide in the column. Here are the exciting results of that challenge plus an extra bonus — a program to display play- ing cards on the screen. Sum of Digits Puzzle The original puzzle asked in how many ways nine digits could be written in three 3- digit rows so that they add up to the proper result. A typical row looks like this: 645 192 tion to the problem was wrong. As Paul H. Johnson, a faithful reader and computer- puzzle buff from San Francisco, put it: "I 837 There are 9*8*7*6*5*4»3*2*ior9! (read as nine factorial) configurations to check in this problem, a total of 362.880. As several readers pointed out. my programmed solu- Bill Barden has written 35 hooks and hun- dreds of magazine articles about small computers . His newest Color Computer project.

I usually wind up learning more from readers 9 letters than I provide in the column. hate to mention it. but I believe your Line 215 is a bit flawed in that it does not recog- nize the possibility of a 'carry'." My pro- gram does not check for such units digits as 7+6=( I )3. This erroreliminated about half of the possible answers. Paul used a high- speed poke with a string in his version. Robert Gault of Grosse Point Woods. Ml, did quite a bit of work on both a recursive BASIC09 program to compute the answers (about four hours from my 20 hours) and. even more impressive, an assembly lan- guage version, which computes all 336 solutions in just over six minutes! Walter D. Pullen of Kent. WA, found an elegant solution. He used an array instead of nine separate variables. Walter immedi- ately checked the units and tens digits to see if their sums equaled the answer digits. If not, he went directly to the next increment. He also noted that "if S1+S2+S3 is correct, then so isS2+Sl=S3." James Jones of Clive. Iowa, was another reader who did a great deal of work on a high-speed solution to this puzzle. His BAS- IC09 version computes the answers in 32 seconds on his CoCo 3. James (who by his comments revealed that he is either a bright computer science student or a professor) used a clever trick. He looped through only the addend digits and not the answer digits. This makes the number of iterations in the loop 9 h =53l,44i instead of 9''=387,420,489, only 7ra of the total. This is possible be- cause with any two addend digits, the an- swer digit is fixed. Another observation he had was that the sum of the two loos digits and any carry from below must be less than or equal to nine. This saves additional iterations. The third observation he made was the same as Walter's above. I have to give James the Son of Perplexing Puzzles #8 Award for his work. His OS-9 solution is shown in Listing 1. Reader Challenge Unfortunately. I was not very specific about the rules in my challenge to arrange the Ace. King. Queen and Jack of each suit (16 cards) in a four-by-four matrix so that no value or suit appears more than once in any row. column or major diagonal. Read- ers didn't know whether I wanted OS-9, BASIC, a physically short program, a fast program, or embellished program solutions. Again, it was James Jones who came through with the fastest overall version without manual calculations. In James' words, his OS-9 program "seems to chug out one solu- tion per second." One of the best non-OS-9 solutions came 54 THE RAINBOW December 1 990 from Waller D. Pullen. It's shown in List- ing 2. Walter writes, "my solution to the main card puzzle finds and displays the first solution in eight minutes. The second solution is found six minutes later, and thereafter a different solution is found every few minutes. There are 1 152 total solutions to this puzzle, all of which happen to be geometrically similar to your example so- lution except that the board is rotated or the suits are switched. All possible solutions will be found in about three days. Note that there are potentially 1 6 factorial board solu- tions that must be checked to find them. If your sum of digits program checked 9! positions and ran in 20 hours, then a similar method employed here would take l6!/9!*20 hours or 132 centuries! To get a workable solution, we must use a little insight. Note that if the Jack of Clubs (J-C) is in the upper-left corner and the Jack of Hearts (J- H) is in the square next to it, then no matter where the other 14 cards are we can't have a solution because a Jack appears twice in the top row. This means we can avoid permutating through 14! (87 billion) boards in this case, and by applying similar checks at each position, we can reduce a complex problem with 16! (20quadrillion) possibili- ties to an elegant program producing swift solutions. The program is completely gen- eral. Try reducing the value of N in Line 20 and solve the problem for a smaller board or add a new value and suit to V $ and S$ and find a solution to the five-by-five board. Whenever a board is found meeting the row and column restrictions, the message test- ing is printed, the diagonals are checked and if OK, the solution is displayed." While not nearly as fast as James' OS-9 program, Walter's is a well-crafted Extended Color BASIC version. There were other entries that worked. Entries that found random configurations that gave one or more solutions and others in which the answers had more than one card value or suit in the same row. column or diagonal. I hope that all readers who responded will not be too offended over my lack of rule definition. In this case, I feel a fair judgment is to declare both James Jones and Walter D. Pullen co-winners, with James winning hands down for speed. Each co-winner will receive 25.ooo.ooo MicroDollars (about $25 at current exchange rates) and. of course, adulation of Barden's Buffer readers for many years to come as readers peruse back issues in front of a roaring fire on those cold winter nights. Displaying Playing Cards As usual, I attempted to do grandiose things with limited graphics for this col- umn. My original intention was to provide nice graphics for the King. Queen and Jack in addition to displaying all of the cards with numeric values. But even the CoCo 3, 640-by-i92 graphics mode is not quite good enough for those face cards, although a reader might prove me wrong. A more modest program in Listing 3 shows a Dis- play Card subroutine that will display any card value and suit at a given point on the CoCo 3 screen. (Thanks to Rick Cooper of Liberty. KY, for the DRAW strings for the suits). Call the program for a 32o-by-i92 CoCo 3 graphics screen with the following parameters: • ZA$ - "vs" where v is the value -1,2, 3. 4, 5, 6, 7. 8. 9. T, J. Q. K. or A - and S is the suit - C for Clubs, H for Hearts, S for Spades or D for Diamonds. To specify the Ace of Hearts, for example, ZA$-"AH". • Z X , Z Y = screen coordinates for the top- left corner of the card in x, v format. To draw the card so that the top-left comer is in the screen center set ZX-160 and ZY-96. The cards are 50 pixels high by 60 pixels wide, allowing you to put five cards per row in three rows on the screen at one time. The actual subroutine assumes that the DRAW strings defining both the values and suits have been defined somewhere in your own program, in addition to a 13-eIement string array V$. One interesting feature of the program is that it inverts the value on the card bottom. You will see an upside down 10, for example, if you specify ZA$-"TC". The suit is drawn upright in the center of the card. This subroutine may come in handy for simulating poker or other card games, providing a lot more useful display than simply a "J-H" type of notation. See you next month with more CoCo topics.

Gold is hidden at a ran- dom location on the CoCo's black screen and after a slight delay a cursor appears on the screen in another random loca- tion. This slight delay is necessary to ensure the cursor and the gold do not appear in the same location. Press an arrow key to move the cur- sor. If the cursor moves toward the gold cache you're hot. If it moves away from the location of the gold cache you're cold. CoCo will print the word gold in big golden letters when you hit the spot. The cursor's movement is intention- ally slow to match the reaction time of a small child. To speed it up, reduce the value of DL in Line 10. To slow it down, increase the value of DL.

Mail allows you to send private messages (or files) to other users on Delphi. This is different from the Forums in which all messages are publicly viewable. To enter Mail, type MA I L at the CoCo or os-9 sig prompt, or type MAIL MAIL at Delphi's Main menu. You can also enter Mail by typing /MAI L at almost any prompt within Delphi. To leave the Mail area, press CTRL-Z or type EXIT at the Mail> prompt. While in Mail, Delphi's slash commands (such as /WHO) no longer work. From Mail you can send a message to someone by entering SEND and responding to the prompts. While you type your mes- sage, remember to press ENTER after each line of text. Press CTRL-Z to send the com- pleted message. If you change your mind while editing a message, press CTRL-C to cancel it. For example: MAIL> send To: gregl . rickadams Subj: I'm back! Hello. Just wanted to let you know that I am back from vacation. I'll see you online later. Eddie "2 MAIL> Eddie Kuns is pursuing a PhD in physics at Rutgers University. He lives in Aurora, Il- linois and works as a programmer and researcher at Fermilah. Eddie is database manager of the OS-9 SIG: his username is EDDIEKUNS. Notice that the same message can be sent to several individuals — just type all the usemames, separated by commas or spaces, of those people you want to receive the message. You can read new mail by pressing ENTER at the Mail> prompt. To find out who the messages are from and what the subjects are before reading the mail, enter DIR. Specific messages can be read by entering the number associated with that message. You can then press enter to see any following messages. If you receive a new message while you are in the Mail area, enter READ/NEW to read them. When you read a message, you'll notice the sender's name looks like BOSiB::ED- DIEKUNS. Most likely, the BOS1B:: part of the name is not important to you — it merely tells you which Delphi computer the sender was logged on to when they sent you the message. You don't need to include the computer name when you send mail to other users — simply specify their user- names. For the curious, bosib means it's machine IB at Boston. Delphi's central location. REPLY and SEND/EDIT are two useful mail commands. Once you have read a message and want to send a reply to the author, enter REPLY. Mail automatically supplies the name of the person you are replying to and the subject of the reply. If you want to edit the message use the S E N D / EDIT or REPLY/EDIT commands. This leaves you in your selected editor (EDT or OLDIE) to edit the text of the message as you enter it. The message is sent when you exit the editor. If you want to reply to a message and include parts of the message in your reply you can enter REPLY/EXTRACT. This returns you to your selected editor with the text of the message to which you are replying. Mail can also be used to send a file, which is convenient if you have edited a message offline or want to send a program or file. First, upload the file (ASCII or bi- nary) into your Workspace. To send the file, type SEND followed immediately with a space and the exact name of the file as it exists in your Workspace. It looks like this: SEND filename. ext To download a mail message enter EXTRACT/NOHEADER//7e«0«l£'.CA7 right after you read the message, filename. ext is the name you want Delphi to use when it stores the file in your Workspace. You can then go to your Workspace and download the file. Use caution when sending and receiv- ing files, however. Delphi allows each user only 50 free blocks (or 25K) of disk space. You must pay for disk usage above that limit. Enter D I R while in your Workspace to find out how much you are using. Once you have downloaded a file from your Work- space, be sure to delete it using the DELETE command. Once you no longer need a message, delete it. Deleting a message may not immediately free its space, however. Mail waits until the total amount of deleted mail exceeds a threshold before purging it from your mail file (MA I L.MAI) in your Workspace. You may want to periodically enter the command PURGE/RECLAIM to clean out your mail file. Purging isn't enough, though. While the message text is deleted, your mail file still contains space for the directory information of the file. If you receive a lot of mail, you will want to occasionally use the COMPRESS command. This removes all unused space from your mail file. After using COMPRESS, go into your Workspace and delete the MAIL. OLD file, which is your old mail file. Within Mail are a number of parameters you can set. Enter SHOW ALL to display your current settings. A very useful parameter is 58 THE RAINBOW December 1990 PERSONAL_NAME. If you want your real name (or a phrase) to be attached to any mail messages you send, enter the command SET PERSONAL_NAME "real name" You can find additional information about Mail's features by typing HELP. Next month I'll describe how to use folders within Mail. This is a convenient way of sorting the messages that you don't want to imme- diately delete. Database Information: When you upload a group of files to the OS-9 SIG database, please direct your sub- mission to the right Topic area. You don't need to submit it to New Uploads. Your group is automatically placed in New Uploads for about a month and will then be moved into the appropriate database area. Tim Kientzle released make, a useful utility for anyone writing code. This ver- sion of make was ported from UNIX. Rick Adams' patch for TlSBdit allows it to run in an OS-9 Level II device window. Finally, the enhanced gf x2 (a new version of gf x2 for BASIC09) uploaded by Kevin Darling is the one Dale Puckett has been talking about for several months in "KlSSable OS-9." Tetris has finally made its way to OS-9 on the Color Computer. Mike Sweet ported it from UNIX to OS-9. Matthew Thompson posted information about the 68070 and vsc chips which make up the heart of the MM/l and TC-70 computers. In the CoCo SIG, Glen Dahlgren contrib- uted utilities that allow you to play sound files created with SoundTrax, as well as a sample which is described as a rap for Kyum Gai: To he Ninja. Marty Goodman posted the first new entry into the Soapbox database area since its creation with a trip report by Phillip Brown (THEFERRET) de- scribing a recent visit to the Soviet Union as part of the University of California at Berkeley Glee Club. □ Database Report Applications: MVFINANCE.AR 07ESRTIMOTHY Tim Faddon MAKE FUNNY ENQUIRER HEADLINES KENCARLIN Ken Carlin Utilities: OEARC EMTWO Paul M.

We hail already explored several unsuccessful ideas and were perplexed on how to accomplish our objective. Several new ideas, including public service an- nouncements and advertisements on local TV stations, were suggested. My son. Brent. was in production on his own TV show and said we should consider making our own show on the Color Computer. He offered to help us with the project and explained that if ours was an educational program without direct advertising we could get the equip- ment and studio at no cost through the Community Access Corporation, which is local cable Channel 42. Channel 42 pro- vides facilities and equipment for local community-related programs. Within two weeks all the necessary forms A local cable- n producer. Andrew Bou- dreau.x, Jr.. has used the Color Computer for over three years. He lives in New Or- leans with his wife and three children, lie can he contacted at 20 Gihh Drive. Chahnette. I. A 7004S. had been completed and we had a commit- ment to produce a I. v week series called Learn Your Color Computer. The excite- ment of this new project sparked our members into action. Member Chris Mayeux decided to write the scripts and host the show. Others searched for Vi-inch com- mercial tapes, lined up technical assistance, collected special cables and connectors as well as other bits and pieces needed. Below are several Color Computer pro- grams created by Chris Mayeux for our show that may be of interest to you. Every TV station requires a one minute header at the beginning of a show. HEADER (Listing 1 ) creates 30 seconds of color bars, a 20 second slate and a in second count- down. Instructions for this are included. CREDGEN (Listing 2) produces the titles for the beginning of the show as well as the credits at the end of the tape. TELEPRMT turns a monitor (BAV or color) or TV into a teleprompter so your host can read the script while on camera without having to memorize many pages of written ASCII tiles (with a . TXT extension) from any word processor can be made compat- 62 THE RAINBOW December 1990 ible with TELEPRMT with SCRIPTO. To be most effective, files must be saved in a 32- column format without words being bro- ken apart on the monitor. WHOSONLN allows for the use of a floor monitor during your show. This allows the host to know who is on hold for up to five phone lines. There is also a single crawl line that can send messages from the con- trol booth to the host while on camera. This was an enjoyable project for our group. While it was interesting to work in an actual TV studio, we discovered we could have the same results with a quiet room, our CoCo setup and one camera. This enables us to do our show on days when we can't use the studio. We made our show by shooting part of a studio/host direct shot followed by a section read directly from the computer output. This process was repeated until we had completed a 30 minute show. We found that by continually putting the camera in Pause mode, a three man crew could do this type of filming with positive results. We finished the last three shows in this manner. With a '/z-inch video camcorder, we shot the show with our own cable adapters and dumped the results to the commercial '/«- inch tape. When using only one camera, frequent change of camera placement will produce a multi-camera effect. There is time during the computer direct to allow for camera and tripod movement for a new angle. A general release from Tandy Corpora- tion should be obtained before any TV sta- tion or cable company is approached about producing this type of show. Releases for music, talent and software used on the show should also be secured. These re- leases are recommended for the protection of your group even if they are not require- ments of the TV station. Use the talents within yourown group to produce a show. Scripts on various subjects can be written by anyone in your group. You can choose one host or. for more club involvement, a series of rotating hosts for the show. The people who work behind the scenes are very important to the overall success of the show. A project of this magnitude requires acommitment from the entire group to be successful. We learned several things during the production of our show that might be help- ful to you. First of all, keep both text and demonstrations simple. Whatever the sub- ject, make sure your segments are related and can be easily connected in the viewer's mind. Repeat instructions often during a segment. Make sure demonstrations of instructions are exact and cohesive. Break subjects into as many simple sections as time permits. For a smooth show, elect one director who is responsible for the overall quality of the production. For assistance in the production of your own show, write to the National Federation of Local Cable Programmers, P.O. Box 27290, Washigton, D.c. 20038-7290. If your com- munity does not have cable, contact the local TV station and ask about the possiblity of airing your show. We of the CoCo SIG in New Orleans hope your group has as much fun as ours with this project, and that the final produc- tion is met with positive results. □ [ Move into the '90s with DiSTD »« [?^®PS^ J Snap©? ©©laiU'ofey I NOW AVAILABLE AT YOUR RADIO SHACK STORE PART # 90-2009 UNDER OS-9: Buffered read /write sector achieved without halting the CPU means no loss of time or keyboard strokes.

This image is present with both my RGB and composite video monitors. I replaced the GIME chip with a new one from Tandy National Parts and the image problem remains. Any ideas? Neal Budd (NEALBUDD) St. Petersburg, Florida By far the most common cause for a problem like this is a defective GIME chip or one that is making poor contact with its socket. Since you have replaced the GIME chip and reseated the chip in the socket as well, perhaps your problem is more subtle. Some kind of ringing in the memory cir- cuitry? I'd urge you to re-check the seating of that GIME chip and thoroughly inspect the contacts on the gime chip socket for signs of corrosion. Neal later responded: // was the GIME chip that was at fault. And apparently the one sent to me by Fort Worth was also defective. The problem was solved when I tried a third one borrowed from another computer. How very unusual. Tandy National Parts seldom sends defective parts. I've been highly impressed with the quality of their service. However. I guess no one is perfect! Glad you solved the problem. Martin H. Goodman, M.D., a physician trained in anesthesiology, is a longtime electronics tinkerer and outspoken com- mentator — sort of the Howard Cosell of the CoCo world. On Delphi. Marty is the SIGop of rainbow's CoCo SIG and database manager ofOS-9 Online. His non-computer passions include running, mountaineering and outdoor photography. Marty lives in San Pablo. California. GIME Extractions I've heard you, Marty, recommend use of two jeweler's screwdrivers at diago- nally opposite ends of the GIME chip as a means of removing it. I used an alternative solution. I fabricated a GIME chip extractor from an ordinary IC puller. I merely filed down the grabbing part of an ordinary IC puller (of the sort available at Radio Shack and most other electronic supply houses) so that they were 'la inch in width and not the '/* inch width sported by the stock puller. At this point I could insert the grab- bing part of the IC puller at diagnonally opposite corners of the GIME chip and smoothly lift it from its socket. Robert Capone Reading, Pennsylvania Thanks for the tips, guys! Wide-Screen Modem Pak How can I make use of 40 or 80 columns on the screen with my Direct Connect Modem Pak? How can I transfer to disk such tape-based games as Pyramid, Raaka- tu or Madness and the Minotaur? Dwane Flint (OEANE) Leesville. Louisiana The software in the DC Modem Pak limits it to 32 columns. If you use other software that drives the hardware of the DC Modem Pak (such as Mikeyterm, Delphi- term and Vterm, all of which have provi- sions for talking to the modem pak ) you can operate the Modem Pak and have an 80- column screen. You'll need a Multi-Pak, Slot Pak III or Y cable to connect both the DC Modem Pak and disk controller to the CoCo at the same time. The DC Modem Pak is such an ill-conceived device I strongly recommend you get rid of it and invest in any inexpensive 1200-bps external modem that can be hooked to the 4-pin serial port of your Color Computer and used with Delphiterm, Vterm and a host of other terminal programs. No Multi-Pak will then be required. You will also get faster, more efficient file transfers. I don't have any how-to series of steps for putting those classic tape games on disk, but the usual problem with ancient tape-based games is those games load at location S600 in memory. This conflicts with the disk buffer area in a disk-based system. Putting them on disk involves off- set loading the games into memory above location SE00 and adding a little assembly language block-move program that, upon execution, block moves the program back down to S600 (or wherever it is normally loaded) and then transfers control to the now properly located program. Gaining Grounds Where is a good site to solder a really big ground wire onto the motherboard of the CoCo? I'm putting mine in an AT-type case and want a site to connect the ground wire. Ted Jaeger (TEDJAEGER) Fayetteville, North Carolina The spots where the clips that connected the motherboard to the back of the key- board used to go are excellent locations. Lands for Extended ADOS I have two older disk controllers that lacked lands 36 through 39 on their 40-pin edge connectors. This presented a problem when I wanted to use them with Extended ADOS that requires Pin 37 (the AI3 line) to connect its I6K EPROM to the CoCo. Some DB-25 connectors have pins that you indi- vidually crimp to wires and plug into blank DB-25 connectors. These pins come joined by a strip of metal. I cut thin strips from this spare metal, bent one end up slightly to facilitate later soldering and bonded them to the controller card using Super Glue in 68 THE RAINBOW December 1990 one case, and Devcon Plastic Welder in another. After the strips were attached I used a file at the edge to make sure the edge was smooth. Both controllers now work fine with Extended ADOS-3. D.S. Ricketts (STEVEPOX) Portland. Oregon Double Sides for TW-80 Several folks have asked me about using TW-80 with double-sided drives. If you load the configure program for TW-80 vow will find in it the following: 370 GOSUB 3890:D2-A 380 GOSUB 3890:D3-A Edit those statements to read instead 370 GOSUB 3890:02-&H41 380 GOSUB 3890:03-&H42 and then run the configure program. TW-80 will now recognize the back sides of drives and 1 as drives 2 and 3. This is the usual arrangement in ADOS and most other Disk BASIC enhancements. However, the drives will still be treated as 35- (not 40-) track drives. Art Flexser (ARTFLEXSER) Miami A very interesting and helpful solution! Long Printer Lines How far can I run a parallel printer cable? /' ve been told that 12 feet is the limit, but I'm in a situation where I really need to run a 25-foot cable. Ernest N. Dotson, Jr. (ENDOTSON) Marmet, West Virginia In most applications parallel printer cables will work fine in lengths up to about 3() feet. Your best bet is to extend such a cable by using a 36-wire male-to-female, 36- pin Amphenol (often incorrectly called Centronics) connector. This assures that all data lines in the extension are separated by grounds. I've heard of people who run parallel cables 50 feet or more without problems, but that is pushing matters and success will vary with the exact circuitry used for the parallel output and input cir- cuits that are joined by such cables. Jameco, of Belmont. California, used to sell a paral- lel cable conditioner specifically designed to make extra long parallel printer cables work more reliably. I believe it incorpo- rated circuitry to buffer the data lines and/ or clean up problems with the data strobe using a Schmitt Trigger circuit. More widely available, albeit more expensive at S150 or so, are pairs of serial-to-parallel/parallel- to-serial converters, that separate your printer from your computer by 100 feet or more by sending the data over a small cable in serial protocol at 19.200 baud or more. This last solution results in slower through- put than a straight parallel cable and could slow things down in graphics-intensive printing situations. Banking Made Eas y Balancing made Simple !

December 1990 THE RAINBOW 69 Disk BASIC/MS-DOS Crossover Can I use 35-traek drives with your program (from the June and July 1986 is- sues) that provides a means of reading and writing ASCII text files from and to an MS- DOS disk on the Color Computer? In that article you also gave an address for Xeno- soft, a company with a product that would read and write alien disks (including Disk BASIC disks) on an MS-DOS machine. I wrote to that address and my letter was returned. Are they still in business? Charles Gable Wayne. New Jersey I'm afraid you must have a 40-track- capable drive to properly read and write MS-DOS disks since MS-DOS has always used all 40 tracks. However, if you are lucky and the file you want to read on the MS-DOS disk is located within the first 35 tracks of the disk, then my program will successfully read and transfer it to CoCo format. Simi- larly I believe that if you first formatted your single-sided MS-DOS disk on an MS- DOS machine (FORMAT IS) and then used my MS-DOS program to write to it, it will work perfectly well as long as you don't try to cram enough files on it to fill more than the first 35 tracks.

Xenosoft, I am happy to say, is still in business and moved to newer and bigger quarters a few months after my article was written. There were some serious problems with mail forwarding due to errors made by his local Post Office, the proprietor tells me. Xenosoft has been steadily adding support for more and more alien formats to Xenocopy, which now permits a PC com- patible to read and write disks from over300 different types of alien computers (OS-9 is currently not supported). Their new ad- dress is 2210 Sixth St., Berkeley, CA 94710. Of LaserJets and DeskJets We've seen IIP DeskJet printers adver- tised for as little as $350 and HP LaserJet printers for under $900. Can either of these be used with the Color Computer? Should one consider getting them instead of a 24- pin dot matrix printer? Bill Condie (DESKMAN) Manhattan. New York David Francis Austin, Texas I've heard from several CoCo users who use the HP DeskJet ink-jet printer and are very pleased with it. At $350, one should seriously consider it when compared to the more expensive (S300 and up) 24-pin print- ers. Note that the DeskJet and laser printers take paper one sheet at a time and may not be suitable for some label and forms printing appli- cations. Additionally, unlike impact print- ers, they cannot handle multiple-form copies at once. But as prices on these come down, they are be- coming attractive al- ternatives to higher- end, NLQ dot-matrix printers. The DeskJet can (with an optional cartridge) be set up to emulate Epson print- ers, which makes it instantly compatible with a wide range of software. I also saw the HP LaserJet II driven by the CoCo- based Microworks video digitizer at one RAlNBOWfest a long P $18.00 time ago. LaserJet printers require com- plex escape sequences to select fonts and no CoCo word processor programs are set up to conveniently use all of their power. But you can use a minimum of their fea- tures and fonts with most existing pro- grams if you are patient about defining appropriate macros for embedded control characters. In Search of RFI Is there a way to disable the TV output of the CoCo 3, thereby reducing RF interfer- ence when using a monitor? James H. DeStafeno Wyoming. Delaware You can disable the RF output by either entirely desoldering the RF modulator box or by cutting the power trace that goes to it under the PC board. I do not recommend this. I think if you do this you will discover that the RFI you seek to eliminate is still present. You see, most if not all, of the RFI from the CoCo comes from transmission from the main computer board and not from the RF modulator. One Cart Short In attempting to perform the CART inter - rupl-strapping procedure that you described in one of your articles, I discovered what may be a simpler way to get the same result in the 26-3124 (new style, smaller) Multi- Pak. You can get at Pin 8 of the 40-pin sockets at the low ends of the four pull-up resistors (R3 through R6). Short these to- gether at their low ends and the strapping is accomplished without having to take out the main motherboard or remove the ground-plane sheet.

I think it is especially useful for those students at the elementary stage of education. With this program a student can enter base angles and actually see the height and base, and the sine, cosine and tangent values vary with each change of angle. This is much more effective than the blackboard scratchings of the Mr. Chalks in my long ago school days. The triangle has a fixed hypotenuse of length 150. You begin with a prompt to enter an angle from 5 to 85 degrees. With The Listing: C0C0TRIG 'COPYRIGHT 1990 FALSOFT. INC. 1 'C0C0TRIG" by Keiran Kenny.

There are 10 programs altogether; four arcade-type games, three databases, two quizzes and one text adventure. Of the four arcade-type games, two of them. Invaders and Doctor Who3, are space invaders shoot'em up games that require a joystick. With Invaders you are moving across the bottom of the screen, shooting at and dodging rows of moving blocks firing at you. Doctor Who3 has you in the air sailing between a moving, shooting laser beam while individual spaceships crash into you. The third game. Drop Pack, is a Tetris- type game that requires you to rotate differ- ent shaped pieces to fill a wall. The fourth game is Grabber. It challenges you to gather boxes from eight corners and place them inside eight rooms without being zapped by other faster moving grabbers who ran- domly appear to undo your work and to chase you. The most entertaining game in my opin- ion is Grabber. This is due in part to its cheerful monkey-grinding music that keeps your shoulders bouncing in sync with the little grabber on screen (at least mine did). The three database programs, Mr. Movie, BabySitter and CoCo3 Recipe Machine. store information for easy recordkeeping. Mr. Movie files the specifics for the home- video movie maker who can't remember which tape he put Aunt Sarah's 94th birth- day party on. For easy access the program records specifically where on the tape that rare footage is squeezed. BabySitter keeps a list of clients, their addresses, phone numbers, kids' names (they're numbered for easy memorization) and pay rate. It then adds your total income to date for each individual client. It gives the business of babysitting a professional flair. The CoCo3 Recipe Machine catego- rizes each recipe and lets you conveniently look for and print copies of recipes for connoisseurs awed by your feats in the kitchen. If you're stingy about sharing your secrets, and feeling a tad bit sly, use the Edit feature todelete one of the recipe's ingredi- ents before printing it. Of course, you may be choosing Uncle Joe's Underground Baked Beans over your best friend. I suppose if you don't make home movies, babysit or cook in any great capacity, the database programs may not prove to be much of an organizational timesaver. However, the babysitting program is a good way to record your earnings for tax pur- poses if you have a large amount of this work and an unswerving loyalty to Uncle Sam. All three programs let you print and save to disk. You can save Mr. Movie data to tape. Time for two quizzes. How well-versed are you in Bible scriptures? OK, then iden- tify the following quote: "Pride cometh before a fall." If you can name the book, chapter and verse, you might be able to handle the brutally tough Bible Scripture quiz program. It's demanding, but have faith and remember that even if you miss all 53 questions, God is merciful. Just humbly move on to the vocabulary quiz. Now, how well-versed are you in the English language? Do you consider your- self to be a glib, recapitulating charlatan or a vociferous braggadocio? I hope neither because one's a smooth-talking quack and the other is a loud-mouthed braggart. Just checking. Anyway, you can be either and still take this vocabulary quiz that includes up to 100 questions. Vocab is fun if you enjoy learning new words. Its one short- coming is that there aren't enough ques- tions and aftera short while there is nothing new to leam. Silvcrcape is Cassette #W's only text adventure. It takes you on a journey to find the lost Lord Silvercape who's been cursed by an evil witch. Most of the adventure takes place inside a castle where death awaits behind uncertain doors. Open one of these and it's back to the drawing board. There are four windows above the text; one for directions, one with graphics showing where you are. one that tells you what items are in the room and one that tells you what items you are carrying. The adventure moves along at a good pace, the riddles and anec- dotes are not overly difficult and the graph- ics window helps you remember your way around, although parts of it you should map along the way. Silvercape would be enter- taining for hours if it had a Save feature. After going through every passage, curse, guard and dragon, you might suddenly find yourself back in the death chamber, which may cause you to put the game away for a week or so. T&D Software gives you a lot for your money. Even if you have no use for the database programs, couldn't care less about broadening your vocabulary and feel that Bible-scripture computer drills somehow detract from the intimacy of such a book, the arcade games and text adventure alone are well worth the price. These programs are designed for beginners, and they come with brief, simple instructions.

The OS-9 sys- tem comes with approximately 30 utilities, many designed to be used as stand-alone programs. An average Unix installation, on the other hand, comes with several hundred small utility programs. Many of these are not especially useful when used alone, but can be combined with other small pro- grams to do very complex tasks. Since the early days of OS-9 for the CoCo, Stephen Goldberg has been writing small, useful utilities and filters. Some have appeared in THE rainbow, usually in Dale Puckett ' s "Kissable OS-9" column. The best of the Goldberg utilities are now available in two volumes from Kenneth-Leigh En- terprises. Each program is small, fast and well crafted. Individually, only a few of these programs would make the average 74 THE RAINBOW December 1 990 os-9 user take notice. But together. The Goldberg Utilities form a sort of tool kit for OS-9. The small programs can be combined using OS-9 pipes to perform some truly amazing feats. Since The Goldberg Utili- ties are available in two volumes, I will treat them separately. But I recommend the purchase of these volumes as a set rather than the purchase of one single volume. The first volume contains 13 programs. Some are simple in both concept and use. These include cl s that clears the screen and val , a decimal-hex-binary base converter. There are also a couple of programs de- signed to stand alone and perform useful tasks. The first of these programs are named pk and unpk. pk is used to pack text files to save space, and unpk unpacks them when needed. Another program in this group is unl oad, which easily removes modules from memory. Also included is an enhanced version of copy. The enhanced version's biggest advantage over the standard ver- sion is that it allows for prompted overwrit- ing of existing files with the same name as the one you are copying. It can also use a large buffer to speed the copy process, especially during single-drive copying. Finally there is append. This program func- tions as a combination of the standard OS-9 utilities bui 1 d and merge, append can cre- ate text files, add to the end of text files and combine two text files by adding one to the other. The rest of the programs can be used alone or with other programs to form new tools. These are some of the most interest- ing programs in the group, count is a small program that counts lines, words and char- acters. It has options to count any combina- tion of these based on the command line parameters entered. Although count can be used to work on groups of files, it is most successful when used on a single file. The same can be said about the programs head and tall. These programs allow you to look at either the first or last lines of a text file, head is especially useful when I need to peek at a file to remind me of its contents. The output of tan can vary based on the command line parameters. It can either be the whole file minus the first n lines or just the last n lines. The programs upper and 1 ower convert files to all upper- or lower- case text. This can be useful for files cre- ated all in uppercase like bulletin board files. The sort utility is an in-memory sorter that takes its input from the standard input path and sends its output to the stan- dard output path. This makes it most func- Free Disk-ZAP with any purchase!

The Unix version is unbelieva- bly powerful, but difficult to use with many of its options. Goldberg's version of grep finds expressions in files. It also has op- tions that allow case-specific matches, and the output can be numbered or totaled several ways. This one will take some time to master, but the results are well worth the effort. I did not immediately appreciate the program named zcopy since I usually use another utility to do the same thing. This utility copies multiple files from one direc- tory to another. It accepts a list of files to copy as standard input and since the file- names are not changed requires only the name of the destination directory for out- put. When used in conjunction with d, -copy is an excellent tool for organizing messy directories. The most useful program of the group is the directory lister, d. Unlike dir, d dis- plays one filename per line and can serve as the first program in a pipe. It can accept wildcards to display certain fi les. It can also suppress those files. This is more difficult to describe than to use. Forexample the line d *.ba? produces a list of all files that end in .ba plus one character, such as tempf i 1 e . bas and newf i 1 e . bak. Adding a - to the filename descriptor causes d to produce a list of all files except these. Used alone d is not a real powerhouse, but when used to supply names to other utilities through pipes it is indispensable. Volume Two consists of 12 more utili- ties that are just as useful as those in Vol- ume One. The easiest to use are code and crypt, code prints ASCII codes of input characters and crypt encrypts or decrypts files for security, dsort permanently sorts the filenames in a directory. There is also an improved version of del that accepts filenames as standard input and doesn't abort on an error. Another enhanced ver- sion of an OS-9 utility is 1 ist, which also accepts filenames as standard input and numbers output. The enhanced version of dump adds options to read files in the execu- tion directory or dumps memory modules. Finally, the version of s a ve is either new or enhanced based on your version of OS-9. Level II does not include a save utility. The Goldberg version has much better error handling capabilities than the Microware version which, in my opinion, makes it a better tool. New utilities in Volume Two include mv and prep, mv copies a file to a new location and deletes the original, prep splits input into one word per line and converts each to lower case. Also included is comm which compares two files line-by-line and then displays the results in column format. Output format is controlled by command line para- meters. The stri p utility removes charac- ters from each input line according to command line parameters. It can remove the beginning or the ending of a line as well as all characters aftera specified location in the line. It is also useful when removing excess information from tabular files and the left margin from formatted text files. The power utility of Volume Two has to be rep, which allows you to repeat a com- mand. The main advantage of rep is that it can repeat an operation that was not origi- nally designed to be repeated. It provides increased flexibility by using a clever argu- ment substitution system that works with other programs that cannot accept multiple input. These descriptions are necessarily in- complete but give an overview of The Goldberg Utilities. The power of these programs is in their ability to work to- gether. For added speed several of these utilities can be combined to accomplish the same amount of work in less time. The utilities are relatively small and can be kept in memory, which makes them faster and even more useful. Each volume comes on a single disk and includes adequate instruc- tions with examples for each program. An appendix explains the most effective ways of combining separate programs into memory-efficient groups that can be loaded into memory and linked to make them a permanent part of your system. These packages go a long way in making OS-9 similar in style to the Unix environment and making you more productive. I really enjoyed testing and messing around with The Goldberg Utilities. I find them useful, fast, expertly crafted and well-designed. I highly recommend them to anyone using OS-9, Level I or Level II.

As a player, you become a bodiless alien life-form whose purpose is to perform 1 good deeds in a large American city. The number of guesses available at the proper verb/noun combinations is extremely lim- ited and you will have to re-start the game approximately every 20 moves. It is irritat- ing to be unable to perform your assigned deeds. Irritation became frustration and soon I was tapping the CoCo keys with a bit more insistence. Veteran adventurers will probably over- look the above mentioned irritations and finish the game in just a few hours. Less patient players who like to break and list a game to follow a programmer's logic will have the added irritation of breaking oui the disassembler to unscramble this game's machine language. % " " " rt . »-.*.*• 1 1.

The white-on-black text is easy to read despite a few grammatical and spelling errors. Each screen is loaded separately from the disk drive (a drive is required for The Entity.) This slows the game slightly, but response time to player's input is very quick. This may be due to an obviously short verb/noun list. I strongly recommend the use of a map after your first few experimental adven- tures. The game counts your moves and records your score. You are awarded 10 points for each successfully completed good deed. Moves must be made very carefully to avoid the ominous Play Again? screen. To display your total points and number of moves used, enter SCORE. Note that this is counted as a move and is probably a waste of your time. STATUS is a command unique to The Entity. STATUS describes the body you currently inhabit. However, the use of this command counts against you as a move and should be avoided once all of the differ- ent bodies in the game have been memo- rized. Finding good deeds to perform is less difficult than finding an order in which to accomplish them without reaching the 20 moves-per-game maximum. EXA (examine) and SEA (search) are useless in the various cells. SPE (speak) is not helpful either. This challenging game can often be quite lonely. But persistence is 76 THE RAINBOW December 1990 rewarded with a nice congratulatory graph- ics display. The Entity could be improved in many ways. First of all. the move number and score should be displayed on each input. An updated version of the screen should be shown after each move to reflect the changes made during play. I would eliminate the unnecessary wasting of moves. For ex- ample, it should not count as a move to look at a newly created scene. I also suggest the author consult a dictionary to correct the grammatical and spelling errors that exist. I am not an enforcer of proper English etiquette, but mistakes such as these can be very difficult to decipher. It is not always immediately clear whether an unaccepted command is really wrong or simply the result of poor grammar and improper spell- ing. Even though author error might be a good alibi when explaining a loss, it leads to massive confusion for the gameplayer. The Entity is a virtually bug-free pro- gram from Biware Enterprises. In all the hours my children and I spent muttering over this exasperating little gem, it did not crash. As is characteristic of games that operate on three letter input. I received some strange responses to my commands. For example, OPE might be interpreted as either "operate" or "open." And LEA as "lean" or "leave." I will not discuss the correlation be- tween the package cost and the satisfaction of playing the game. I will instead leave that up to individual analysis.

There are thousands of printers still being used that have no built-in Near Letter Quality (NLQ) mode. This makes it difficult for computer users to make pres- entation-quality printouts of text files. Rather than investing in a new printer, CoCo users may now obtain NLQ without the cost. Clll Lettrex is a program that reads an ASCII text file from any CoCo word processor and converts the printout to NLQ text in any one of 14 nlq fonts. There are a few things you will need besides an Epson or Epson-com- patible printer. You*ll need a CoCo with 64K or more memory, a mouse or joystick, and a disk drive. Two disk drives will speed operation. Clll Lettrex can also be of value to users with printers supporting NLQ fonts, such as Star NX- 1 000, who want more and /or different fonts. Clll Lettrex is easy to use and well- designed. The program functions as a filter for ASCII text. I tested the program on an NX-1000R printer. It performed well and printed quality text samples in the different fonts. In fact, the fonts were sharper and clearer than the manual portrayed. One thing that Coless Computer Design might consider is higher-quality printing and copying for their own manuals. When the program begins, you are greeted with an opening screen and three point-and-shoot pull-down menus. Pick a baud for your primer, a font and a pitch. Then load a file and print it. This entire operation takes about as long as reading this paragraph. Once the font and baud have been set, there is no need to re-set them unless it becomes necessary due to the length of time you are in the program. the Rulaford Research BBS Ys»y'S/£ — ^e^ EE -\ — c s >:x///,r7 y — ? — i- ■4 \ V 'V*^ ^ — -n^ — ■=: — ^ _ Introducing a new M/D/ Music BBSi Use your computer, a terminal program, and a modem to communicate with other users nationwide Download public domain programs for the CoCo and IBM Try out new music programs by downloading demos Order products on-line Set your modem for 300, 1200, or 2400 baud, 8 bits, no parity (call (61 9) 690-3648 if you need assistance) No connect fee!

This is a 2'/:-line file that allows you to see what your text will look like in the font you have chosen. If you like what you see. select Print with the mouse and the font loads and prints. Press E to abort printing. P to pause printing and C to con- tinue printing after a pause. The program automatically senses whether or not your printer is online. If your printer is not online, click on the file box and repeat the procedure from (he beginning. Also, there is good error trapping that will give you a big error box displaying an appropriate message and return you to the main screen. So if you forgot to put a disk in, or format it, or left the drive door open, or typed the wrong file name, you can quickly recover. This is a very useful feature. The documentation that accompanies Clll Letirex is 24 pages long and has 18 figures to assist programming needs. There are also several font tables for font size and estimation of characters-per-Iine. The only complaint I have is the quality of the print in the manual itself. If you have a word processor that leaves its control codes visible, your document will not print correctly. You must hide the control codes so they are not visible on the screen. Your files will then print in the prescribed order. This is a package that is well worth the required investment. (Coless Computer Design, 1917 Madera St., #8, Waukesha, vvi 53186; 414-549-0750; $24.95 plus $3 S/H) — Jeffrey Parker Desktop Publishing CoCo3 CHI Pages Enhanced Version 2.0 I recently had the pleasure of stacking some pretty exciting CoCo desktop pub- lishing packages against one another in an article for THE RAINBOW (May 1989). If Clll Pages Enhanced had been part of that ar- ticle, it would have received some high marks in certain areas and low marks in other areas. Then in February 1990. Jim Issel, a noted RAINBOW reviewer, looked at the original Clll Pages. He was not entirely thrilled by it. Many of his comments about the program produced responses by the program's author. Walter Bayer of Coless Computer Design. Walter took the com- ments to heart, and in less than six months he had completely rewritten several of the more criticized features of his program for an enhanced version. These enhancements and other improvements to this program are the focus of this review. Clll Pages is a full-featured desktop publishing package for the CoCo 3. Like its predecessors, Clll Pages attempts to put as many different features as possible on the same screen simultaneously. At the same time, it relies on a wimp (Windows. Icons. Mouse and Pull-down menus) environment to acquaint users with creating and editing. cm Pages operates with either 1 28K or 5 1 2K , though limited to one and three pages of editing respectively. All these tools in one place is good, but even with the required Tandy High Resolution Joystick Interface and a mouse, the left column is so crowded that you can often accidentally click on the wrong icon even if you are pointing at the right one. After a period of adjustment. I could work with these newly enhanced features. Probably the most important upgrade to the package is its speed and smoothness of operation. With Version 2.0 the speed is dramatically improved. A hefty rotation or horizontal flip has been reduced from a several-minute wail to one of several sec- onds. Another enhancement is the require- ment that the user choose the appropriate printer baud from within the program. This must be done when the program is first started. The manual has grown from 68 to 83 pages. The package now contains a sepa- rate reference card that is very useful. The text still has grammatical errors and is rigorous in places, but the overall quality has improved. The font, as well as the quality of printing and reproduction make the manual appear "muddy" and unclear. The edges of the letters are poorly defined making the text difficult to read. The manual was printed with Clll Pages, but is not an accurate representation of the quality print produced by the program. Clll Pages is now distributed on two double-sided, double- density disks. Both sides of each disk must be backed up before the program can be used. Printer support has remained the same and the Undo function is still limited. If you use the Invert Box feature, the only way to undo it is to exactly match the size with the Invert Box feature. It seems as though there should be a better way to do this. The Text pull-down menu has been replaced with a Graph pull-down for clip-art and picture files. The Text feature is still slow, and if you go too fast, you lose characters. The user interface takes some getting used to. but is workable. Once an action on a panel has been completed, there is more than one way to get your frame back. The WIMP environment usually negates the ne- cessity of having to read the manual, but with Clll Pages you must read the book first. The program comes with more than 15 fonts, dozens of clip art images as well as enough unique graphics and text-import features to make it a strong contender in the CoCo desktop publishing market. What Clll Pages lacks in finesse, it makes up for • HI Pages is a ful I -featured desktop publishing package for the CoCo 3. With Version 2.0 the speed is dramatically improved. in muscle and brawn. Jim Issel said the program fills a gap in CoCo DTP. He also said this gap must be filled. I agree with both of his statements. This is an interest- ing and full-featured product that still needs further streamlining, but it is a good solid value and will get the job done. New to Clll Pages is the Clll Clip An Set 2 package for cm Pages Enhanced Version 2.0. This is an outstanding value. Although Clll Pages is already loaded with clip an. fonts and borders, this set of clip art is excellent in both quality and quantity. There are 672 custom-designed images featured in categories labeled Creatures, Miscel- laneous, RAD Concept, Weird, Symbols and D & D Fantasy. This is my only criti- cism. Each 14-cIip file is labeled with one of the above, but they could be broken into 78 THE RAINBOW December 1990 other themes such as Holiday. Religion, Sports. Business, etc. The accompanying manual provides a printout of each clip-art file to find what you are looking for. If you prefer to use the computer, a file viewer called V 7 is included with each clip-art disk. I was disappointed with the program at first, but when 1 loaded the art and printed it on a Star NX- 1 000 with the standard driver in CM Pages, I was impressed. This is a very good value for clip-art and/or CM Pages Enhanced users. Clip art requires CM Pages Enhanced Version 2.0. Upgrading from Version 1.0 costs S 1 2, and you must return your original system disk and sales slip, cm Pages En- hanced Version 2.0 requires a I28/512K CoCo 3, a High Resolution Joystick Interface, a mouse or joystick, at least one disk drive and an RGB or composite monitor. This package will not work with TV. A mouse and at least two disk drives are recom- mended, as is a printer. Make sure your printer is supported.

This pro- gram requires a 5 1 2K CoCo 3 and OS-9 Level II. Mitlti-Vue, a mouse and a color monitor are optional, but recommended. The high- resolution display mode used by this pro- gram makes a monitor desirable. As Planet Engine begins, the screen displays celestial bodies along the ecliptic plane. The ecliptic plane is a band of the sky that includes the section inclined 50 degrees north of the Earth's equator to the section declined 50 degrees south of the equator. The main view shows planets, stars and constellations. A line traces the southern horizon, with the zenith pinpointed by a cross. The relative locations of the various bodies are determined by the time and also your location on Earth. Planet Engine dis- plays stars, planets or constellations. Scroll bars can be used to change the time by hours or days. The program contains three pull-down menus. The first menu provides access to the same features available under the Tandy icon in the Multi-Vue menu. The second menu toggles on or off the display of stars, planets and constellations. You can also change the date and time as well as your location on Earth. The time can range from approximately 32.700 B.C. to 32,700 a.d. And your location can, literally, be anywhere on Earth. The planets' orbits can be viewed in an overlay window. With the third menu you can view each planet in an overlay menu. The only drawback of this program is the lack of detail in the pictures of indi- vidual planets. These views do not fully exercise the CoCo's graphics capabilities. Planet Engine is an extremely easy program to learn. I discovered many of the program's features through experimenta- tion before reading the manual. This pro- gram can be operated with a mouse, but it also accepts keyboard commands. A 13- page manual that accompanies the program is thorough and well-organized. The man- ual takes you through backup and installa- tion. It also gives you a sample question, information on the data displayed and in- structions on using the various program features.

The disk includes the program and its graphics files, in addition to icon and appli- cation information for Multi-Vue users. The program is not copy-protected and can run from any directory or subdirectory on a hard disk. Since the program is fairly disk- intensive, a RAM disk or hard drive will increase the speed of the graphics. Planer Engine uses the Multi-Vue interface, but can run from the command line in a four color graphics window. Plane! Engine is a well-written pro- gram. The first time I used it. I accidentally failed to copy one of the many data files to my hard drive's subdirectory and the pro- gram still ran flawlessly. The only thing missing was a small section of the sky. As a test I ran the program a few more times with randomly selected data files missing and had the same results. Planet Engine contains a wealth of pic- torial information. It has helped me in locating constellations during observations of the night sky from my yard. It also allows me to watch the movement of constella- tions, planets and stars over a period of time. This program would be an asset to teachers in grades 4-12. amateur astrono- mers or anyone else interested in the cos- mos. For its usefulness and extensive data. Planet Engine is a bargain at S24.

Why not make your CoCo a central control for a complete in-home burglar alarm system? Or perhaps you are not interested in these ideas, but would like to further expand your knowl- edge on the inner workings of the CoCo and have some fun, too. If any of the above applies to you, then Connecting the CoCo to the Real World by William Barden. Jr. may be just the book for you. For a couple of years now I have enjoyed reading William Barden, Jr.'s column ("Barden's Buffer") in THE RAINBOW, as well as his books on assembly language and graphics for the CoCo. So I was excited about the opportunity to review his latest book. Connecting the CoCo to the Real World. I was only slightly disappointed to discover that a few of the projects in the book are simply transplanted from his monthly column. My disappointment was short-lived, though, as I soon learned that there are enough new projects to keep his fans' interest. The book and its projects are designed with the novice in mind. Knowledge of digital circuits and programming is not required to build, or use, any of these proj- ects. All you really need to know is how to enter and save a program on your CoCo, as well as how to cut and solder wires. If you want to expand or improve any of these projects, though, you will need an under- standing of digital circuits and program- ming with both assembly language and BASIC. After you've read the book and built some of the projects, it may be beneficial to leam even more about digital circuits and programming. One chapter is devoted to the work of the CoCo's analog-to-digital circuitry. Other technical information on the inner work- ings of the CoCo are scattered throughout the book. This information is designed for those who want to learn more about the way in which the projects and the CoCo work in tandem, but it is not necessary to build or operate the projects. Although after build- ing a few projects, your interest and curios- ity may increase enough to pursue a deeper understanding of the more technical as- pects of these projects. The cost of the projects vary, but none are outrageously expensive. All of the projects can be built for less than S20 with average costs ranging from less than S5 to slightly more than $10. These costs do not include a proto-board which is needed for several of the more complicated projects. This is an inexpensive item that can be purchased for about Sio from your local Radio Shack. For those who are familiar with Mr. Barden's column, the book will be easily understood since the projects follow this same style. For those unfamiliar with the Barden style, it can be summed up as the KISS (Keep It Simple Stupid) principle. The instructions are not step-by-step, but they are easy to read and follow. Barden offers suggestions on possible applications and expansions for the completed project. He also encourages exploration of your own ideas. I had a few problems with the book. First of al 1 1 thought it was too short. I also found problems with the first few projects. Not with the projects themselves, but with Mr. Barden's failure to thoroughly explain for- mulas used to help analyze the readings and find resistances. These formulas are given with little explanation of their origin. While it is possible to build and use these projects without this knowledge, further expansion and changes to the projects without this information could be difficult. It may be necessary to do some reverse engineering to discover the origin of the formulas used. Connecting the CoCo to the Real World is a good book that offers some atypical ideas on how to use the CoCo. The book is easy to read and the projects are both useful and fun. If you're not careful, there might even be some learning amidst all the fun.

Products like The Micro Works DS-69 series have sought to serve this interest, bin most of ihese products have been strictly black and white devices with no color capability. There remains an unfilled demand for a digitizer that actually captures color im- ages. The Rascan digitizer is a product thai might just meet this demand. This product, developed in Australia and sold by Super- soft, allows you to capture and display full- color pictures as well as high-quality black- and-white pictures with a CoCo 3. Rascan even allows you to produce images in 3 i>. The Rascan digitizer is a bit different from most other digitizers. It plugs into the CoCo 3*s joystick ports instead of the expansion port and can. therefore, be used without a Mulli-Pak Intel lace. The box has a video input (RCA-type phono jack) that works with almost all home video equip- ment. The unit also has brightness and con- trast controls, a power sw itch, ami a second switch to control a II Iter that is used to keep the color portion of a TV signal from inter- fering with the process. To set up the dig- itizer. Iced your chosen video source into the input and plug the two cables into the joystick ports. Then put a copy of ihe driver disk into Drive 0. type "RUN CONFIG" and press ENTER. Aflerselling the monitor type (for an RGB or composite monitor), press ii to save the settings. "RUN BOOT" starts the program and pro- duces the Main menu. You must then select the desired mode. Choose 640-DV-200 with dithering for 16 levels of gray. 640-by-20t) with four actual gray levels. 320 by -200 with 16 colors or the 4096-color mode. The mm<> color mode works only on a 5 1 2K system, but the normal black-and-white modes work in either I2XK or 51 2K. To begin the digitiz- ing process, gel the video signal ready, select the Capture Image option and sw itch on the Rascan unit. The menu disappears and a thin bar sweeps from right to left on the display. The next step is to adjust the brightness and contrast controls to gel a clear image with gooil gray tones. Nexl, use the -m.i and CTRL keys to center the picture vertically. The left and right arrow keys center the image horizontally. When Ihe bardisappears at the left of the screen, press BREAK, switch off Ihe Rascan unit and press BREAK again. The image is now in memory and can be saved to disk. Rascan black-and-white image Hies can be loaded \atoMax-lo, CoCo Max ill ot Color Mm 3, Kul ihe 16-color, false-color mode is ihe preferred method for importing files into ihe latter iwo. The video source can be almost any- thing that provides a composite video sig- nal, but since the system takes about 15 seconds to scan Ihe image. Ihe image must remain stationary during this period. The best way lo take pictures of stationary subjects or art work is louse a camcorder on a tripod to tape the subject for a few minutes and then play the tape into the Rascan unit later. In some cases you might be able to freeze a frame on ihe VCR, but this will not work well on most decks so it"s advisable not to use slill pictures. Laser videodiscs will do just fine if the disc was recorded in the W) minute c\v mode. Many newer play- ers have a digital memory, which will cre- ale still frames from any disc.

To achieve color, the software takes three separate scans of the image (one each forred, green and blue) and drops them into separate ram buffers. It then displays each in sequence 60 times a second in their respective colors. This is accomplished through a set of color filters that comes with the system to take three separate shots of the subject on tape, one with each filter held in front of the lens. The software allows you to select which buffer to use at any given time and get the images into the right places. When this has been completed, the 4096-color display mode puts the full color image on the screen. The 3-D mode works much the same way except you take two pictures without filters (one for left, the other right) with the camera moved four inches to one side between shots. Then drop the images into the red, green or blue buffers. To view the result, use a pair of red/blue or red/green 3-D glasses, which may have been bought a few years ago to view a special 3-D movie shown on local TV. The yellow/purple glasses used for the 1989 Super Bowl half- time show won't work. The Rascan system produces high-qual- ity digitized pictures, though good results take some time and practice. Tonal grada- tion is very good once the brightness and contrast are set up properly, and resolution is acceptable at about 250 lines both hori- zontally and vertically. (This is somewhat better than the horizontal resolution of a typical home VCR.) A minor flaw is that the area of the image captured is about 83% of the vertical area (200 lines out of a total field of 241) and about 75% of the available hori- zontal area. This can be moved to any desired portion of the image, but it may be a limiting factor in some cases. As the different ratios would imply, the image is somewhat stretched horizontally and people may appear fat. The color and 3-D display modes have a problem in that the field-sequential tech- nique used to display two or three buffers at once causes a strong flicker effect. This can be reduced by darkening the room lights and turning the monitor or TV contrast down, but some flicker will still remain and may be somewhat bothersome. The flicker has no effect on still photos of Rascan displays taken from the monitor screen as long as you use a shutter speed of 'A second or slower. Printer drivers are available for Epson- compatible and CGP-220 printers. Reviews of these optional products are forthcoming. Despite the flicker in the color modes and the somewhat tricky brightness and contrast adjustments, the Rascan system is the best Color Computer digitizer I've ever seen. I have no qualms about recommend- ing it to the serious CoCo 3 user.

Now we will cover the same concepts with the C compiler. Most of the techniques are similar, but there are differ- ences. There are even a few pitfalls thrown in for good measure. In review, we discov- ered three basic types of I/O operations with BASiow: interactive, sequential access and direct access. Interactive access uses the INPUT and PRINT commands to get data from the user and print it on the screen or printer. I call it interactive since the INPUT command al- lows you loedit your input before you press ENTER. Also, both commands are primarily intended for interactive prompts and que- ries to the user. Sequential access uses the READ and WRITE commands to read and write ran- dom-length sequential records that are of- ten stored in memory as a single structure. If you recall our recent discussions, each field and record is terminated by a known character in sequential access files. Keep in mind that these two commands do not readily lend themselves to printing prompts on the screen or printer due to the use of field and record terminator characters. Direct access uses the GET and PUT commands to read and write fixed-length records, which are also stored in memory as a single structure. This allows you to quickly locate and retrieve any record within a file by calculating the offset of the record. This is accomplished by multiplying the record number by the size of the record. //; addition to being OS-9 Online SlGop, Greg Law enjoys programming on all types of computers and has worked on systems ranging from the C11C0 to the Burroughs Bt>/W super mainframe . He lives in Louis- ville. Kentucky. There are only two basic types of input/ output operations in C. buffered and un- buffered. Even though there are only two types of operations, the differences be- here are only two basic types of input/output operations in C, buffered and unbuffered, and the differences between them can be very confusing to the novice. tween them can be very confusing to the novice. These two operations can be fur- ther divided into dozens of subcategories. These subcategories are grouped into rou- tines for singular data types (character, integer, long and floating point), routines for multiple data types, specialized data conversion routines and miscellaneous routines. The good news is that there are direct counterparts to basicto i/o commands. For simplicity's sake we will first examine these. The differences between Disk basic and BASIC!) 1 ) were covered in the September iwo issue of therainbow (Page 28). In the first example, a very simpl istic command is given to open a file. The same operation in C is very similar: Int path: path - open( "datafile.dat". I): First, a variable is declared that will be used to hold the returned path number. The open! ) function is called with the name of the file and the access mode as arguments. The access mode specifies the operations that can be performed on the file and is either I for reading. 2 for writing, or 3 for reading and writing. Note that open( ) re- turns the path number as an integer value, much the same as BASIC09. The big differ- ence here is the method used to obtain the returned value. Also, the openO returns negative one (-1 ) if it cannot open the file and. unlike BASIC09. C performs almost no error handling for you. For this reason, the value relumed should be tested to deter- mine whether or not an error occurred. 1nt path: path-openCdataf1le.dat". 1): 1f(path — -1) exlt(errno): In this case the routine attempts to open the file, then tests path to dctemiine whether or not an error occurred. If an error is detected, the program is terminated by calling exi t( ) with the value of errno as an argument. Many of the library functions, espe- cially those dealing with I/O. are little more than delegates between you and the operat- ing system itself. For example. open() does nothing more than place the address of the filename and the access modes into the registers and performs the I$0pen system call. The operating system attempts toopcn the file and returns the results to open( ). If the file is successfully opened, the path number is relumed in one of the registers December 1990 THERAINBOW 87 Submitting Material To Rainbow Contributions to mn rainbow are wel- come from everyone.

If an error occurs, the carry Hag in the condition codes register is set and an error code is placed into one of the registers. In this case. open( ) stores the error code in errno and returns -1. You probably think the process of open- ing a file and checking it for an error condition is long and drawn out. One of the prime advantages of C is the ease with which such tasks can be shortened. In the above code path is assigned the value re- turned from open( ) and compared against -I. Shortening the logic a little, we basi- cally have the following form: a - b-. if(a 1) Do you remember the basic laws of alge- bra? Given an equation, the value for a given variable can be determined through mathematics: 2x + y = I2 + .V+ v lv-.v + y= 12 +y 2v-.v=12 .v= 12 Let"s apply this formula to our code. In the following section, a and b are used to represent an arbitrary variable or function. a - b; lf(a — -1) (a - b): if(a — -1) lf((o - b) — -1) By now you must think I've gone stark raving mad. If you do not understand the connection between the laws of mathemat- ics and Ihe process I used to derive Ihe short-hand notation, follow along closely as the technique unfolds. Given the assign- ment statement a-b. isn't (a-b) the same? The parenthetical enclosure of the assign- ment statement has no effect so it must be the same. And isn't (a-b) the same as a? It is since a and b are both the same. Then the results must be equal. The parentheses are added to the assignment statement so that the assignment operation is performed prior to the comparison. Whew! Checking our work, the original statement is: path - openCdatafile.dat". 1): 1f(path 1) Since path is assigned the value returned from openO. we can assume these are equivalent. Therefore, the following must also be true: The only difference is thai path is com- pletely dropped from the formula, which makes the results useless. In other words, Ihe file may be opened bul ii isn't helpful since we lossed ihe path number into the bit bucket. With this logic in mind, we should be able to finalize Ihe statement as: lftpath-open("dataflle.dat".l) — 1) Although this looks correct and may in- deed be mathematically correct, it is logi- cally incorrect. The reason is a four-letter word known among C programmers as precedence. This one curse word renders the above statement useless. Because the comparison operator (— ) is higher on the precedence chart than the assignment op- erator (-). the above statement is the same as: temp - openCdataf1le.dat". 1): path - (temp — -1) That is. if temp is assigned a value of - 1 , the comparison isTrue ( I ). Otherwise the com- parison is False (0). A bizarre side effect causes path to be assigned a value of True or False based on the results of the compari- son. Because of the rules of precedence, we must enclose the assignment operation within parentheses to force the compiler to perform the operations in the desired order. Our final result is if((path-open( "datafile.dat". 1)) — 1) exi t(errno): Now you know why precedence is often referred to as a four- letter word. I urge you to locate a book with the precedence chart in it. Copy that page, cut it down to size and paste it on a wall or monitor within easy reach. And it may help to remember my motto. "If in doubt, add parentheses!" Remember, it is belter to be safe than sorry. Stay tuned next month for the continuation of our discussion of file I/O. By then we should have a few examples to better illus- trate these concepts.

Howie Carmel, New York We're glad we could be of service, and thanks for the kind words. Printers and Hard Drives Editor: What kind of serial-to-parallel printer interface would 1 need to connect my DMP- 1 33 printer to my CoCo 3? I am interested in purchasing one and do not know that much about the parallel interfaces. I understand that there are different sizes, but I would like to know what size to get. I am also interested in purchasing a hard drive for my CoCo 3 and 1 don"t know how to purchase one. What do I need to have one and what comes with it? I understand it cuts down on having to use software all the time. I would like to know how one is used and what programs can be put on it. My CoCo 3 has I28K. but I have been thinking about going 10512K.I would like to know whether ornot it would be worth the money. Dwaine Acker P.O.
