EDITORIAL

EDITING OR CENSORING?

I've been asked to bite my literary tongue. I had intended to publish a rather biting and pointed editorial aimed at editors of newsletter who "edit" or change writers articles to suit their tastes or particularly to promote products they sell. Remember, editors, your job is to correct raispelled words not put words in other writers articles. If you rewrite a piece the way you want it, then it is YOUR article not the original authors', so don't put his name to it because that's not what he wrote.

BYE SMUG BYTES

Sorry to see that the newsletter of SMUG is going to cease publishing. The Milwaukee group has put a lot of good stuff out over the years and Bill Heberlein deserves a lot of credit for his efforts. Bill, if you still want a place to print your views or info, Sine-Link will be happy to supply a platform for free.

YO! AMERICAN READERS

When you mail stuff to George, please, please fill in the customs declaration listing your package as a gift and/or with "no commercial value". Otherwise George must pay our GOODS & SERVICES TAX on whatever value you assign if he is to retrieve it from customs. Recently he had to pay over $5.00 GST to get a box of disks that had been mailed to him.

NESQLUG VISIT

Saturday, June 27th, turned out to be a perfect day for a barbegue as four members of NESQLUG visited with TTSUC members at Hugh Howie's house in Burlington. Joyce Blaho, Al Boehm, his wife Dorothy and their friend Gary all made their way from the Boston area for an informative afternoon meal and bull session. Particularly interesting was Al's CST Thor QL clone with its built-in drives and memory and his graphic demonstration of a program called "Molecules" not to mention a game or two of his own design.

Thanks to Hugh and his wife for the hospitality. See photos next page.

That's all for now. . .

An occasional series for the occasional programmer. Copyright Q Alan Pywell 1991. PART TWO.

In part one I covered the basics of writing a procedure and passing para- meters to it. I will have a little more to say on the subject shortly but first a few observations (or warnings - call them what you like)

From my experience of programs it seems it is all too easy to fall into the trap of "over-procedurising". By this I mean writing a procedure for every little bit of your program. This is worse than writing no procedures at all.

A couple of examples from a program in our library will illustrate my point.

DEFine PROCedure KEY:V$= I NKEY$(- 1 ):END DEFine

I fail to see what this achieves. The program still needs to check that a

valid key has been pressed, -erhaps there's a procedure to do this

I daren't look.

If you're going to write a procedure put something in it!. Another line reads:-

DEFine PROCedure paused: FOR j=1 to 500: NEXT j: END DEFine

This really is ridiculous - what's wrong with PAUSE X? The author has re- invented the wheel, a common failing. PAUSE is a good keyword, to be used in the main body of the program - it is a waste of time and effort to write a procedure to give a delay.

The program is so full of unnecessary one-line procedures that is had to be compiled in order to run about as fast it would have done uncompiled if it had been written properly in the first place. (I shall cover writing for speed at a later date)

All I'm saying is "Think a little about what you're typing". You should of course break up your program into the jobs it has to do and then write a procedure to do them but this doesn't mean a procedure for every line.

It is wasting effort to write a procedure for a tiny job or a job that will only be done once or twice. There are no hard-and-fast rules about this, use your judgement. As a rough rule-of-thumb a procedure should do more than one thing, like the procedure for getting user's input and checking it, or save a lot of typing.

The other observation I want to make is that this series has had little forward planning and is not meant to be a definitive guide to SuperBasic. I am hoping for feedback from readers before I do any planning........

I wrote most of this whilst waiting for members to write expressing interest after my recent letter in QUANTA. I am adding this paragraph after the eagerly awaited response came flooding in from fellow-members. I have replied to them both to say that I will not be writing any more

SINC-LINK

SUPERBAStC - YOUR POWERFUL FRIEND PASSING PARAMETERS (again)

Page 2

You may have noticed in the May issue that when I called the procedure that the parameters sent to the proc (they were called min and max) were not enclosed in brackets yet the recipient (the actual procedure) had brackets around them:-

GETKEY 1,4 blah blah blah

DEFine PROCedure GETKEY (min, max)

I suggest you get some cardboard and write someone a stiff letter about this.

It's not so bad really - you'll get used to it.

Here's a bit of a program for printing some text on the screen:-

PAPER 6: INK 0: AT 10,10:PRINT "This is a message" PAPER 1: INK 6: AT 12,10:PRINT "So is this"

Every time you want the program to print something you have to type something like the above. If you decide to alter one of them later you've more typing.

It is more convenient to call a general-purpose proc and to give it the information it needs (pass it some parameters)

1000 WRITE1, 6,7,10, "Have you seen my Batman outfit darling9" 1005 WRITE 2,0,8,4, "It's in the wash - wear your pajamas" 1010 some more prog as usual

and here is the procedure

10000 DEFine PROCedure WRITE (INK_COLOR, PAPER_COLOR, ROW_N UMBER,

COL UMN_N UMBER, MESSAGES) 20005 INK INK_COLOR: PAPER PAPERjCOLOR: AT ROW_N UMBER,

COL U M N_N UMBER: PRINT MESSAGES 2C0*0 END DEFine

As you can see the passed parameters tell the procedure the ink and paper colors to use, where to print the message and the last but not least, what to print. Any place in your program that you want to print something just use a line: WRITE, followed by ink and paper colors, where at and your text. It's easier to alter it later if you should wish to, say, change the ink color.

You could also pass a channel number and a FLASH number but I'm not about to do everything for you!

I'm sorry but I can't put it off any longer. "I'm throwing some new words at you and they're extremely erotic, sorry exotic.

GLOBAL LOCAL SCOPE

Normally you can alter the value of a variable anywhere in a program. Yes, I know you know, give us a chance. Take the previously-used variables min, max. Please take them, I'm fed up to the teeth with them.

SINC-LINK

SUPERBASIC - YOUR POWERFUL FRIEND

Page 3

They are not terribly sacrosanct in that it would not matter if a part of the program that is not part of a procedure used them. They could be used in any part of a program. You may want to pad out a string if it's length is less than min, for instance, by adding spaces or whatever until its length equalled max. Or a thousand and one uses. Whatever you do with min and max, a call to GETKEY will set them to the desired values for that particular call to the proc. Their SCOPE is said to be GLOBAL. Don't ask me why "they" chose the word "global" which of course means "world-wide". Our field of view is somewhat narrower - GLOBAL simply means "use it anywhere in the prog.". "But that's obvious" you say. Watch it, clever-clogs, I'll be asking questions later

I suppose you already know that the variables are stored in a special area of RAM which someone, in their infinite wisdom, called the variable area. (Area for the variables, get it? No?, well it's an area.. )

Suppose that, for your own foul purpose, you had the power to say "look here, you, this variable is to be used only in procedure X." Have i got news for you! You can. You simply tell QL that "this variable's SCOPE is LOCAL to procedure X". Just another little rule - you must tell QL inside the procedure, hardly worth mentioning, really.

DEFine PROCedure GETKEY (min, max) LOCal min, max

REPEAT LOOP V$=INKEY$(-1) etc,etc

There's just one thing wrong with the above - it won't work! You cannot declare as LOCAL parameters passed to the procedure. Think about it - they're not really local are they? But you can use any other variables inside a proc and ensure that they are confined to the proc.

The QL User Guide says "Defining variables to be LOCAL allows variable names to be used within functions and procedures without corrupting meaningful variables of the same name outside the function or procedure." So now you know. Up comes a chorus of "Can you have two variables with the same name then, and what's a function?"

First things first - yes you can, as long as one of them is LOCAL to a function or procedure. The LOCAL one exists only within its procedure or any procedure called by that procedure. It is lost when the procedure

ends.

A function is., you don't really want to know, do you? There's one on next week at my local Town Hall. I'll have to leave the other kind for another day.

You ./ill have noticed that sometimes I have omitted line numbers. If you wrote a SuperBasic program with no line numbers you would almost have written a program in Archive. SuperBasic is a good language but there are many much better and they don't have line numbers at all. I'll have more to say about Archive and the line numbers at a later date. In the meantime, don't be frightened of Archive.

ZX81 RESOURCES - Moving RAMTOP Rene Bruneau 21 June 1992

Noraally, to lower RAMTOP, you have to poke values into addresses 15388 and 16389 then NEW the coaputer to change RAMTOP. If you have loaded a prograa that required PAMTOP to be lowered before starting, you end up reloading the prograi because NEW also wipes the wenory clean. What is needed is a prograi that dynamically shifts RAMTOP without affecting the aeaory after a program is loaded. I located this routine in an old issue of COMPUTE! and fiodified it to use the saie intonation transfer that was presented in the last newsletter. The aachine code is relocatable.

Enter Listing 1, RUN 100 to input the ic data in Listing 2. On completion, enter S, and confira that the checksua is 3099. You say now delete line 100 to the prograa end. Save the prograa several tines. On running, the prograa asks you for the address where the code will be located. Entering a nuaber will relocate the ac.

To love RAMTOP up or down froa the original setting key in

RAND (New RAMTOP), ENTER

PRINT=USR lac location), ENTER To confirm that the routine works type the following line

PRINT PEEK 16388 + 256 X PEEK 16389

The nuaber printed should aatch the RAMTOP that you set with RAND. If you wish to enter the routine in a second REM stateaent after an existing REM then disregard lines 10 to 80, and renumber the rest so that you don't inadvertently over-write existing basic lines. You will also have to

establish where the first byte of the routine will be and revise line 100 to suit.

ZX-81 - SOUND ANALYSIS

This machine code program for the ZX81 draws graphics illustrating sound. Sound is fed in on the Ear socket. To load the program, create a REM line H5 characters long. Use any Hex loader to enter the code. The program is executed by RAND USR 16526.

If you want the computer to draw one graphic and then return to Basic type:

POKE 16551,192 (Enter) POKE 16552,0 " POKE 16553,0 "

Otherwise the computer will clear the display and draw again. The program returns to Basic when any key is pressed. The sub-routine at H082h ( 1 651 U ) gives, in C register, the frequency of the tone on the Ear socket .

Ronald M. Cavin II 17 41 Marshlyn Ct . Columbus, OH 4 3 220 U.S.A.

Dear George,

I have been involved in some very interesting things over the last several months which might catch the eye of some of your readers. Many of us in the Timex/S inclair world have had to leave our beloved machines for, of all things IBM clones!! I happen to be one of those who was pushed into this mode a few years back. I now own a 386DX clone, with 70 meg hard drive, SVGA monitor, HD 3 1/2 and 5 1/4 disk drives, 2400 baud internal modem, and merit mouse. It's a pretty impressive machine, especially since I put it together with several scrapped PCB ' s . My cost for the system was very little.

You might ask, "What is he telling me this for?" Well, enter a public domain program called JPP-B2! This a Spectrum emulator written for anyone who has a 386 (or above) machine, with a VGA monitor! The program was written by a gentleman named Arnt Gulbrandsen in Norway. You should find a copy of the program enclosed with this letter. Feel free to distribute it.

Basically the program causes the 386 to operate like a Z80. Before you can fully utilize it, however, you must make a copy of the Spectrum Rom, and get it over to the IBM. There are several ways to do this. You could enter the Spectrum mode, and write a simple BASIC program to copy (POKE) the rom code from 0 through 16384 into ram beginning at location 40000. A second approach is to use an assembler and write a short machine code routine, using the LDIR command, and copy it over. In fact, some assemblers have the ability to copy code between locations with simple resident commands, thus eliminating the necessity for wr i t i ng any move routine.

My preference was to enter this direct command: SAVE "SPECTR.C1" CODE 0,16384. This copies the rom to tape. (You cannot use this method to copy the Timex rom, since the first 8K of rom is paged. You get 8K of EXROM followed by 8K of HOME ROM). When the SAVE is complete, rewind the tape and enter this command: LOAD " " CODE 40000,16384. This puts the copy of rom into ram, beginning at 40000, extending through 56384.

The last step is to make a copy of rom to disk. Enter the following Larken command: RANDOMIZE USER 100: SAVE "SPECTR.C1" CODE 40000,16334. Now we can move full steam ahead. Next time we will transfer the rom code from the Timex to the IBM. I'll discuss this fully next article. Meantime, refer to NOV-DEC '91 and MAR-APR '92 issues of SINC LINK for a preview. t*y&4 , tfo^*rriAn ft fee

text87 plus4 version 2

bj Hugh H. Howie.

1 guess I was probably one of the first to get plus4 which is the updated version of text87, which is a vast improvement on Quill.

Plus4 (version 1) as it originally arrived crashed with great frequency especially with the last line erased. There were other problems also, but that was the principal one. This caused me to lose a lot of work which t had spent a lot of time putting together. I was most annoyed and got a letter off to Software in short order with my complaints.

Now at this point I would like to make something quite clear, when I review a program or hardware, I will write of my experiences, I will not hide or gloss over any fault I find with the item under review. I feel that if t find a fault I should mention it, then others will know what to expect should they purchase that item. I will not at any time make glowing comments just to please the purveyor or producer of that item. Having made that point, let's get on with the meat of plus4.

After my letter to Software a reply was not long in coming, with VERSION 2. This is the version which should have been sent out in the first instance. Not only the crash problem was solved, but also a lot of other little ones which made Ver 2 much slicker to work with. Some of the menu commands had been altered slightly, and also some additions had been made for better control.

According to the short note which came with version 2 the problem which caused

the crashing " also affected the

integrity of the text formatting data stored in _T91 documents'* What this means is that any documents produced with version 1, are not able to be loaded into version 2 other than as an ASCII file; any documents so made lose all layout setup etc as provided in the original document.

Version 1 came with a good manual. It states that the manual is "a learning aid

for the use of text 87 and is not

meant to be a specification for the use of

text87." Version 2, as I received it, did not have an up-dated manual, just a one page note that a few changes had been made. I understand that Ver 2 as now issued comes with the Ver 1 manual, plus two extra pages. I have not seen the extra pages as yet, but would like to.

One thing missing from the manual is an Index, I made up my own index from reading the manual and from the use of all the menus in the program, so that I can refer to this index and see where what is going to lead me.

Another item missing from many manuals are samples. Plus 4 has three, a "Sample Mail_merge", "Sample Document", and a "Sample Manual" All very useful and informative.

Version 2 is touted as not requiring the aid of a manual as there is plenty on- screen help available, and that the menus are sufficient. I find that the manual is of inestimable value, even altho' it is for version 1. There are many instances where you must refer to the manual to get any action; for example, try setting the "layout" of a document with headers and footers (now known as "text Sections") without using the manual! It is a complicated although very efficient operation but the on-screen help is not of much value in this particular instance. OH! yes, the on-screen manual can be printed out for better study, but it is still not as complete as the original version 1 manual. And the slip of paper which comes with version 2 is not as complete as it might be.

No doubt the later purchasers will be given an up-dated manual. I intend writing to see if one is available.

Selection of type and fount to use is very much simplified. There are lots of Founts supplied, and lots of Printer Drivers to select from. There is no reason you will not find a Driver and a Fount to suit your taste.

When Loading a file, (and also when saving a file) when you are asked for the name of the file, by pressing one of

SINC-LINK

the Arrow keys, a display of the files on the default data disk is displayed. Selection from this list is by use of the Arrrow keys, and then the file is loaded automatically.

Many of us know the frustration of having a stack of three or four disks and only being able to save to #1 or #2. Version 1 was one of those, but ver 2 will save to whatever you wish almost, e.g. RAM8_. DEV, NET, WIN etc.

Speed of scrolling up or down is really fast. It is possible to scroll one line at a time, or by paragraph or by page. Search or Search/Replace is equally fast and efficient. Found before finger leaves key.

There is an excellent Spelling Checker available with two English dictionaries. Also a French , a German The ' Q t y p _d ic tio n ar y ' is easy to use, but there is also a 'bigger'_dictionary which should just about satisfy the needs of the most fastidious and demanding writer. Unfortunately this 'bigger' dict- ionary takes up a horrendous amount of memory, and is intended only for those with the Gold Card or Mega ST's. However, the regular dictionary is adequate. Replacement or amendment of any given word is at the users discretion or automatically on demand. Sorry, it will not correct typing errors on its own! Should your document contain words which are not in the dictionary then it is a simple operation to incorporate them in the regular dictionary, or even to make up a "specialised" dictionary of your own.

Any spelling checker is only good to a degree. Should you use the word "their" instead of "there", or "wine" instead of "whine", or if you type i instead of I, no spelling checker is going to get you out of that one! Still, it can assist in pointing to real bloopers. Yes, it can be handy, but I still prefer to rely on my own knowledge such as it is.

When you wish to Print the document, you are given an option to preview it just as it will go to the printer. This is an excellent feature as you can see on

screen exactly how it will appear on paper. One serious flaw I came across is that I cannot find a way to print a couple of lines, it has to be the complete page. With the original text87 you could print three or four lines if so desired.

It is possible to have more than one document in memory at the same time, and to switch from one to the other, and also to have a portion of each document on-screen at the same time. You can have parts of three or four documents on display! Alright it can be a bit messy on occasion, but it is still very handy if you wish to work one document and have the other there for reference.

text87 in its original form took a lot of work to learn how to make the most of it. The transition to plus 4 is not too hard to accomplish. I would imagine that plus 4 is probably much easier to learn from scratch than text 87.

The manual takes 56 pages to tell you how to do what, so how am I supposed to do the same thing in a couple pages? There is only one way to evaluate this program, and that is to try it for yourself. I am sure you will not be dis- appointed

Plus 4 is an excellent word processor and I would not like to be without it. This is what the serious writer requires. I can ask for nothing more than what we have here, sure I have a couple of beefs about it, but those are not really serious beefs, and with more acquaintance with the program, those should be eliminated.

I am sure glad I spent the money getting plus4, I have spent some time mentioning version 1 and version 2, that is only to show you that Ver 2 is all that it should be. I would not be without plus 4. I am not an expert on word processors, but this sure hits the spot with me. I can hardly ask for more. Plus 4 is first class. The way we all like to go. Expensive- Yes . Extensive- Undoubtedly . If you like to write get plus 4.

2068 &3OTD BCllEEZI

(with a 1000 supplement)

Dale Fritz, SEATUG

Most of us know that, the 2068 has a second independent screen (known as Display File 2-see pg 248 of the 2068 User Manual), but methods to easily use this screen are not widely known.

My interest was in after drawing some elaborate Hilbert Curves on the main screen, I wanted to print a Menu to give choices of Copy or continue in various modes. The Menu would destroy the main screen and there wasn't much room in Lines 22, 23 for a Menu. How could I use the second screen for my Menu and then go back to the first screen with my picture intact?

The 2068 Technical Manual, Appendix C, has 16 pages of machine code concerning the second screen, where one can Clear Screen, Set Cursor, Print Character, Scroll, etc.

My needs were much more modest.

Stan Lemke, of Desktop Publishing fame, published a small program, "Blink", in SyncWare News which considerably simplifies use of the second screen. There are three routines :

A. Read a modest amount of data from a Data statement and initiate the second screen.

B. Build a Menu (or whatever) on the main screen and transfer it to screen 2.

C. Bring screen 2 back to screen 1 for editing and improvement. Use routine B to return the improved version to screen 2.

As one could guess, there are some limitations. LIST, PRINT, PLOT, DRAW, etc. will not work in Display File 2. Even more disconcerting, you can't get any messages from the computer when using the second screen.

All the messages are being printed on the main screen and you aren't there.

The answer, say, in case of a Menu, is to provide safeguards around an adequate INPUT response and get back to the main screen.

1000 SUPPLEMENT

One can save and immediately print back screens with the 1000. It involves saving the screen in a string, then simply printing the string to restore the screen.

Consider the main screen as AS and the second screen as BS . Using the following routines and PRINT AS, PRINT B$ , a very' comparable demo to that above could be made.

8990 REM . .SAVE MAIN SCREEN . .

9000 DIM A$(70A)

9010 FOR K=0 TO 21

9020 FOR L=l TO 32

9030 LET A$(L+32*K)=CER$ PEEK (P

EEK 16396+256*PEEK 16397+L+33*K)

9040 NEXT L

9050 NEXT K

9060 RETURN

9090 REM ..SAVE SECOND SCREEN.. 9100 DIM B$(704)

9150 NEXT R 9160 RETURN

Postscript: Alternately, there is a 2068 WINDOWS Demo in the SEATUG Library, which could be studied and used for a Menu instead of the second screen. However, if I had remembered that sooner, we would not have had these neat screen subroutines.

ZX81 - SEARCH AND REPLACE

Searce and Replace will search the screen for a character you specify and replace it with any other. Load this machine code routine into a REM staement in the first I ine of a program. The I ine should be no shorter than 23 bytes long. Search and Replace runs in a 16K ZX 81 only.

RAMBLINGS

Did anybody ever get a " MOUSE " going with a I understand that a certain type of mouse quite well with the 2068.

The QL User Guide in the concept section TITLE of " JOYSTICK " Page 27 says that the two and CTL2 will accept two Joysticks .

MORE RAMBLINGS " QL

If you have been following the saga of CARD here , you must have gone through the in reading the blow by blow account of Hugh with both of these projects.

However I think the result certainly effort. I haven't been convinced as yet to but the

text 87 and GOLD same agony I did Howie's struggle

was worth the get a GOLD CARD

I did order and have received " text87plus4 that is updated version of text 87. I must say that the result of

all the efforts of the producers as well as Hugh's contribution to the project, have ended up with a worthwhile WORD PROCESSOR . Much easier to use and with prompts available, it is a dream to load and to start producing some outputs. I have already used the " mail merge " option to write 5 letters ( all the same excepts for the addressees " with a minimum of bother.

I certainly can recommend the new version of text87plus4.

Louis Laferriere QL - Ramblings

Over the years a steady contributor to our " SINCLINK " newsletter and cur QL library has been Mr. Swenson. I believe he now resides in California,, Well, Eome o-f his programs are quite successful, e.q. LISTER, QLcrypt II etc. . He even dabbled in writing a new language for the QL, " small C I am afraid that was too much for me. However he also gave us " MAILLIST " which by itself works quite well , with the exception that the " ZIP " and " STATE* " did not fit our requirements. So I reworked the file with the end results that we can now use it far our Canadian mail ling standards. I did not bother changing " STATE* " for " PROVINCE* " but I did enlarge the display on the"" screenl "so that the full name of the province will be shown =»nd printed and nnt- just the first " TWO LETTERS '« as in the american system. Also our postal code is a. combination of diqits and letters therefore I Added " * " to the " ZIP " field.

T will be giving a copy of the revised program to HUGH HOWIE to include with our library.

One of the "must have" utilities that any self-respecting software "hacker" needs in his/her arsenal of tools is a DATA line maker. Although there are several available , especially for the Spectrum ROM, my favorite one appeared in the May 1988 Newsletter of the Capital Area Timex Sinclair Users Group by H.E. Weppler. I have simplified it and moved the CODE to a safe area below BASIC.

This program performs the opposite of POKing CODE into RAM addresses from a DATA line. It will create a user

specified DATA line containing CODE extracted from a user-specified range of addresses. For example, if you have some machine code, font code, or' an ASCII text file located somewhere in memory, and would like to extract the code and place it into DATA statements to use in another program, this simple program can be MERGEd or LOADED to do the job. Enter the following BASIC program and be sure to RUN line 9950 to initialize the short machine code. The program will then automatically RUN. You will be prompted for a line number to assign the DATA statement.

Any line number will do if it is less than 9900. Next INPUT the starting address of the CODE you wish to extract. Lastly you will be prompted for the end address of the range of bytes you want to extract. I recommend that you don't extract more than 150 bytes at any one time. If you do,

editing that DATA line will be difficult. If your CODE is more than 150 bytes long then keep track of the line numbers and address ranges and RUN line 9900 until you have all your CODE placed into BASIC lines. 'The machine code used in this program is completely relocatable. To quickly see how this program works, try this:

RUN line 9900. At the prompt, enter 10 (ENTER.) . That means we want to make a DATA statement at line 10. The next prompt asks you to enter the starting address of the CODE. Let's extract the CODE from this program which begins at address 24311, so input that number. Next, INPUT the end address of the range of addresses we are extracting, ie. 24352 (ENTER).

Now you're done. Compare your result with line 9965. If your CODE is lengthy, break it down into several DATA statements by re-RUNning line 9900 several times.

Have fun I Happy TIMEXing. . .

REDUCE NUMBER OF DISKS IN USE WITH TK2

b/ Hugh H.

Before I get started let me remind all you 'gurus' out there this is not for you, it is for the fellow who has not explored TK2 'cause he was put off by tiny type and Hi-Fi hype.

The first thing I wrote back in January on TK2 was something that made me look further into TK2, and the last issue, (March 92) expanded on that. I have no intention of getting in too deep, so don't expect too much.

So often we find that things in a magazine or newsletter are far and away beyond what we the innocent little starter can comprehend. We read of "jobs" and things like that; as far as they are concerned I tried to forget that as soon as my kids were able to look after themselves. Butt, to get back to basics, most of us are only too happy if we can use some simple little things to show others how smart we are. And how good the QL is.

Now smartness is not always how we dress, it could be how we ADDRESS a problem.

Take the number of disks we have which only have one little teeny weeny itsy bitsy program on them and which are not often used, but we still keep them "just in case". How do we address the problem of too many disks doing too little.

Many disks contain programs of only two or three parts and one is always a 'boot', and we can have only one boot on a disk. So if we wish to put a lot of those programs on the one disk, we have to do it one at a time, and make a different name for the boot in each case, which can take a long time. Or, we can use the WCOPY command from TK2 and transfer those programs to an omnibus disk and give them all a different PREFIX at the same time, almost ensuring immunity from duplicates occurring. Still retaining the integrity of the original title.

Say we have a program called 'CHUCKLES' which has three parts to it, and it is the ONLY program on that disk, we would place the working disk in flpl__, and the target disk, (the one we are going to copy to) in flp2_ and type in:-

WCOPY FLP1_/FLP2_CH_ <ENTER>

This would copy ALL the files on flpl_ to flp2_ and give them the prefix of CH_ so CHUCKLES would become CH_CHUCKLES.

So a DIR on the target disk (flp2j would

look like:_

CH_CHUCKLES

CH_BOOT

CH_CHUCKLES_BIN etc.,

In the above command I did not give a title 'from', and take special note that I did include an _ after the prefix 'CH'

Next step is to place small SPACE or separator under this program, and we do this by - watch the quotes - typing :-

SAVE "FLP2_ "

Note one space after the £Lp2_. The next time we do this would require two spaces after the flp2_. Of course you do not have to use the SPACE you could use the or ... or === or whatever.

Next we could send over LAUGHTER with LA_ and GRINS as GR_GRINS. Get the idea?

Now if you wanted to remove the prefix, you could use RENAME, e.g.

RENAME FLP2_GR_GRINS,FLP2_GRINS

and GR_GRINS is now plain old GRINS again.

If you wished to change the name on the GRINS 'suite', you could use:-

WREN FLP2_GR_,FLP2_

You should use a DIR or WSTAT after each operation to see what is happening.

There are many ways those two commands can be used, try a few experiments on your own. Just watch your commas and '_' and quotes. All are VERY important.

If you want more of thus, or if I have made an error, please write and tell me.

Q L I P S

I often think we should have more key-in materia] in our Newsletter, but I do not like to use programs which have very long listings as we (I at least) sometimes get tired when typing those long listings. So if anyone has a little gem which could be of interest, send it in. This way we make the Newsletter more interesting for all, and at the same time we can enlarge our QL Library.

Come to think of it, some folks may like to have long listings to type in, so if that is the case, let us know and I will dig out some long ones especially for you.

I must admit that shortly I will run short of short listings to use, however here is a shorty which is very colorful in color, but still interesting in Monochrome. Try it in both mode 4 and mode 8.

This will put on screen a host of elipses in a host of different colors and a host of different sizes. (I had onions for lunch therefore I tend to repeat myself today)

Must be getting near to spring, my father (93 last December) is starting to work in the potting shed getting ready for when the snow goes away, not that we have had much this year. Yet. Here is something to brighten your day.

This comes from DEM0_1 disc in the QL Library.

Disk Copy Problem

Help Wanted . (No - Not you Hama!)

One of my Disk setups is as follow s:-

5 1/4 80 track 1440 Sectors

3 !/2 80 track 1440 Sectors

5 1/4 40 track 720 sectors

I am using a TRUMP CARD and the little plug -in card to give extra drives if necessary, using the top port.

Problem:-

When I try to WCOPY from flpl_ to flp2_ the £Lp2_ invariably continues to run and will not accept the copy. Sometimes it even tells me "Bad or Changed Mediium"

When I WCOPY from £Lpl_ to Raml_, and then from Raml_ to flp2_, The copy has no problems.

WHY?

QL - IBM Compatibility CARD?

1991 - Miracle Systems produce the Gold Card which gives the QL so much more power and speed and versatility.

At the same time there are strong rumours that Miracle are also working on a Graphics Card.

1991 - Software announce PLUS4, that wonderful Word Processor.

1992 - Latest whisper 1 hear is that Miracle are also working on a card to allow the QL to be compatible with IBM. No details available at the moment.

Look Out little blue,

The QL is taking a Quantum Leap at you!

Long Live the QL The QUEEN of all

Dear Out-Of-Town Members:

Well, what have we this month, I mentioned my eye operation in the last letter, Everything is fine now,

I know what needs to be first in this letter, A reminder to members living in the U,S, You must fill out and attach one of the green customs forms when you send me material, or return club material, Jeff mentions it in his newsletter briefly. Recently I have recieved a couple of packages, and have had to pay GST (Goods & Services Tax, for the uninitiated!) on their presumed value.

Two things: You should put a rather nominal value on the slip, I suggest 50 cents per tape/disk, AND you should tick off that it is a gift item.

One package was bulky and had 10 disks in it. There was no value stated, so Customs valued it at $11, They then charged 80 cents GST and added a $5 service charge. Another package had no indication it was a gift, and no value stated. Customs assigned a value of $50 and billed me $3.50 GST,

One of our club members, Ronald Cavin, has sent me a suite of disks which essentially are designed to allow a Spectrum to be emulated on an IBM! He has also written a series of articles for the newsletter, about this. The first article is in this issue,

If anyone has a PC, and is interested in seeing these disks, drop me a line. Come to think about it; I'll have to get someone else to make a copy: I don't have a PC, I'll ask the first member who borrows them to make up a back-up copy!! There are 3 disks, Ronald says you need a 386 or better, to run this emulator.

You may notice that in the newsletter there is a 3-part listing of newsletter contents. Sort of an index of contents, I've been asked how to get copies of some of these articles, I had not thought about this before, but I suppose we can supply members with photocopies of the pages these articles appear on, for 5 cents a page, plus any postage if incurred in mailing them, Be sure to mention article name, and what issue it is in.

Or you can order back issues of the whole newsletter if you want, for the same 5 cents per page,

I had a letter from a non-member asking for some help with the Larken Maxcom program. That's a BBS operating system for the 2068, There are two versions, one for 300 baud operation and the other for 1200 baud. This person sent me still another version which Larry K, had written, Designed to work with two other programs called I0traj,B1 and 0trajs,B1, I have done a bit of work on them, and have written back for more info, But have any of you heard of IOtraj.BI & 0trajs,B1 programs? Or version of Maxcom, B1 that starts at Line 8000, not Line 10? I'll write a newsletter article about this matter, when it has been resolved,

Tim Swenson, who is a member of the Capitol Area Timex User Group and who publishes a small journal/ news letter called "QL HACKER", has sent me a copy of two recent issues of The Hacker, and also a QL disk that has all nine issues of this journal on it. Anyone interested can either ask me, or if you have QL you can drop a line to Hugh Howie.

I received a letter from a Don Lambert, Editor of ZXir Clive Alive and a TTSUC member.

He writes, "I don't know if anyone will be driving or flying south from

the TTSUC to attend the Dayton ComputerFest the 29th and 30th of Aug, but T/S will be there, Frank Davis and Paul Holmgren will have tables there, Bob Swoger has gotten a table in my name for T/SNUG and CATUG. I hear tha^ Andy Hradesky or at least someone from Colorado will be there, Frank Davis and I will have rooms at the RED ROOF Inn (North, I think it is) which is nine miles from the Hara Arena where the Fest is held. That place is big!"

Incidentally, it seems possible that two persons will be there from TTSUC, That is to say, Jeff Taylor and Rene Bruneau are talking about it,

I have had two members send me games recently, In one case it was on tapes, the other on disks. Needless to say, I am up to my eyeballs with them, A couple of things about them, though, The disks had a menu program, that I rather liked, I have been refining it considerably, and I shall make an article for the newsletter giving the listing and describing the features of it, Interested in games, anyone?

I have been further refining a program sent to me by member Joan Kealy , which contains a mass of information about Timex computers and the Timex scene. The refinements make it suitable for the Larken system, and I shall put it onto a disk in the Larken disk library. The programs are called TIPSAM,B1 and TIPSNZ,B1,

Although the tape libraries have not grown, the Larken disk library is up to disk #50, I'll try to get catalogue of the most recent 10 disks off to known Larken owners, with this newsletter. Other members, ask if interested ,

We have a new member who writes me that he is into the hobby of rocketry, and uses the TS1000 and 2068 to assist in launchings, thrust measurements, etc, He has offered to write articles on the topic, if we were interested. I said we certianly were interested!!

I'm delighted to see that we have some ZX81 stuff for our ZX members, Andre Baune has come up with another nice issue of ZX-91, which we have included in our n/1, Thank you Andre, Andre is also a member of our club,

I am behind again in my communications with OOT's, But I shall try to be up to date by the time you get this newsletter. If you are awaiting something from me, drop a line.

I'll close this Since re ly , George Chambers

off now,
