_ START this month’s final look into the inner workings of Atari Basic with a small apology. If you read my Checksum Buster article in the April issue, as a good many of you did iudging by the mail we have received, you might have been a little upset to find the message APRIL FOOL I

all over your screen. Sadly, re-assembling a line of text from a three digit checksum is impossible - there are many different persplashed

mutations which can generate the same value. Apartfrom bein a lesson in never trusting anyone —gnot even me it does teach us quite a few useful things about how Basic works. When you used the program, typing LIST just caused a page of jovial text

with no line numbers or command words to be output. So, how can a program exist in a tokenised — or SAVE format — file if it contains noth-

that could have

ing

been

correctly

tokenised in the first place? The answer is that Basic only checks for the validity ofa program line when you type it in or use ENTER. It therefore assumes that any SAVEd tokenised file must have been error checked at the original time of entry and is now syntactically correct. What Checksum Buster does is create a file which is correct in terms of the individual tokens and pointers,

but makes no sense as a logical program. To understand it further, let’s take a look at the file format used by Basic when you type SAVE or CSAVE. The bulk of it consists of the tokenised program lines themselves in the format that we have been looking at so far. The variable name table must Of

which represent the bytes address of the variable name table will always be 256 because this table is 256 bytes from LOMEM. These seven offset values take up the first 14 bytes of the file, and are followed by the variable name, value and statement tables containing all two

—

the actual program lines. The final element of the file is the current statement line -— numbered 32768 — which contains whatever command Basic was currently processing.

Normally the last thing being worked on before a file is written is the SAVE command itself,and thisis what you would usually expect to be found here. This

file format is shown in Figure II, but you might like to see it in action for yourself by typing in the listing. As written it will only work on disc files

But if you know, why not drop us a line? The only other information required by Basic is the contents of the zero

machine code routine. RUN, the program will check which version of Basic you are using and read the various rombased text tables into the pseudo string arrays CMD$ and OP$. These will later be used to display the correct text for each available token. Once this is complete you will be asked to enter a filename. Use the full name - such as DZ:FlLE.BAS — of the Basic SAVEd file you want to view. The first 14 bytes will then be read in and the rest of the file scanned to obtain the correct NOTE and POINT contain

Basic file created by last month’s Buster you’ll start to see how the seemingly impossible was created. All the lines of text were stored in the variable name table with the final character of each in inverse video to fool Basic into thinking they are just long variable names. So you’ve discovered that a complete program can’t be made from its checksums, but you might have learnt more about the way that Basic functions and also that the tokenising system is not quite as rigid as it first looked. There is a well known saying which applies very well to computers, and especially to Basic: It's impossible to make anything complete|y foo|proof because fools are so ingenious.

HAVE kept the program to solve the gambling problem simple. When run, an evening at the roulette table iust flies by. Line 100 defines how much money you have in your pot, with line 110 setting the size of the initial bet. If you, like, you can put input statements in both those lines to vary the amounts when run. We can keep track of the largest bet we have placed with the variable LBET. Next we read in all the red numbers from the DATA statements into the array REDl). The casino might close before we are through so the total number of spins of the wheel possible is tracked in the variable TSP. Similarly the number of spins actually used is recorded in SPIN. A logic variable BUST indicates if we have enough money to cover our bet and line 210 sets up the victory pot — the amount we have when we decide to give up for the night. So now we enter the casino and

THE Atari cassette system is beautifully designed and always works per-

fectly every time. And if you believe that you’ll believe anything. How often have you typed in along program and CSAVEd it, only to find later that there's a fault on the tape? A cassette file can be tested in only one way — by trying to load it. But this destroys the original program in memory, so if the file happens to be faulty you've lost all your hard work. All kinds of things can go wrong. 10

If,

those used in several previous cassette autoboot routines we explained in our articles in Atari User, so you may already have a ?le with

them on. The DATA at lines 40 to 60 holds the autoboot creator code and lines 150 onwards contain the verify routine itse|f, Type in Program and —with fingers crossed _ CSAVE a copy. Insert a blank, fu||y re-wound cassette and run the program. After a few seconds you will hear the famiiiar double beep. Now fo||ow the usual CSAVE procedure and the machine code routine will be written to cassette in autoboot format From now on you’ll use this new tape, so program | shouldn’t be needed any more. But keep it in case you’ve made any typing errors and need to change it later. Before you can use the verify routine however, it has to be loaded into memory. Re-wind the tape with the autoboot program on it, switch power off then switch on again while holding down the Start key. When the single beep sounds, proceed as for CLOAD and the autoboot program will install itse|f before Basic takes control, changing the screen border colour to prove it. Incidentally, if you don't like the colour change, replace the 143 at line 160 with o and make a new autoboot tape. You can always double-check that the routine is installed, by typing pR|NT PEEK(1821) the result should |

be 104, You can now carry on programming just as though the new routine wasn’t there. When you’ve finished use the usual CSAVE, SAVE”C:” or LIST"C:” commands, and your program will be saved to tape. Now’s the time to check that it's a good copy. If the file was made using CSAVE, then type X=USR(1821).This simulates CLOAD, with its short interrecord gaps. If you used SAVE ”C:” or LIST “C:”, then type X=USR(1821,1). This lets the routine work with long inter-record gaps, to simulate LOAD “C:” or ENTER “C:”. in all cases the file is loaded 128 bytes atatlme into the cassette buffer. .

top-notch Verify routine

would

check each byte against the Basic pro-

gramin memory. However,thiswould

make the code much more complex, and greatly increase the autoboot loading time. Apart from which, it's extremely rare for just one or two bytes to be corrupted — if the file will load at all, it's almost certain to be a good copyTo keep things simple and minimise typing, we've taken the soft option — our routine simply reads the file and does nothing with it. During the reading process you Will hear the .

HOW THE PROGRAM WORKS -

you're into machine code you might like to take a look at the source listing. lf nothing else, it will remind you what a cassette autoboot file looks like. The header starts with 0, then contains the ?le length in 128-byte sectors, followed by the load address and intitialisation address. On power-up, and before Basic takes control, the operating system does a JSR to the sixth byte after If

LOADADR. This puts it at COLDST

where the cassette motor is turned off and the Carry flag cleared to indicate a successful boot. The RTS at line 300 returns cont trol to the operating system, which then doesaJSR to the initialisation

address. This resets MEMLO and changes the screen border colour to let you know that the routine is installed. Pressing Reset repeats the JSR to INIT, reinstating the new MEMLO and border colour values. The RTS at line 380 hands control to Basic, leaving the rest of the

machine code routine safely tucked away and ready for your USR command. The USR routine itself starts at line 410 with a PLA to detect whether or not a parameter was inserted. If not, it assumes that the file to be checked uses shorthGs. lf any parameter was passed then long lRGs are selected. The speleled mode is programmed by

storing either $80 or $0 into the second auxiliary byte of 1068 #7. We chose this lOCB since it's the one used by the operating system for most external l/O transactions. Lines 630 to 750 load the ?le, 128 bytes at a time, into the area reserved for cassette lIO — CASBUF. So long as no error occurs, the 6502 processor's Sign flag remains at until the end-of—file. Consequently line 750 will loop back for another chunk of data. When the reading process stops for any reason the Sign flag is set, so the routine drops through to ENDTST

lf you come into contact with any of the lasers or the walls you will be instantly disintegrated. Remember to watch the level indicator at the top of the screen. The intense radiation generated by the lasers will destroy your Thunderfox if you take too Jlong getting through.

located in its head and you must shoot it 10 times to blow it up. This is hindered by the mobile wall that moves up and down in

vessels that you can just ignore. Also atthe bottom of the screen is a status line showing your score, lives remaining, weapon in use and the current level. The main action takes place at the top of the screen.

An extra ship is awarded every 5,000 points scored, and your total score is calculated depending on a number of factors, such as

The game is joystick controlled, allowing you four directions of movement up, down, left and right. if you are travelling ?at out when you push fonivard or will backwards you accelerate o'r decelerate relative to the movement. However, when your craft is moving at its slowest speed, when you pull in the opposite direction it will flip over and reverse its travel. The fire button is used to activate the on-board lasers —

The sound effects are well implemented and there is a catchy main tune. When your fighter launches from its hangar you get a superb side on view of it an original feature.

Your programming problems solved by ANDRE WILLEY

THIS month the first letter comes from Bryan Kennerleywho is based at Rhyl in Wales. He has a few questions about some puzzling aspects of the Atari floppy disc system. lam currently writingadiscsector editor and while doing so I have uncovereda few unusual phenomena. Firstly, on reading the directory of Alternate Reality The City (disc 1, side 1), two directories appear to be displayed in a random order. Investigation reveals that on reading the directory sectors (361 to 364) the same thing occurs. How can these sectors hold one set of data on one pass and a completely different

—

set on the next? Also, while writing the DLI routines! made extensive use of the Dos 2.5 ramdisc on my 730XE, and in doing so

discovered a seemingly pointless function. If a working DLI is disabled by setting bit 7 of location 54286 to zero (using POKE 54286,64} before accessing a D8: ramdisc ?le, the DLI miraculously springs back into life again. Is this essential to the ramdisc’s operation, or is itjust a bug? would like to include in my pro— gram the capability to detect, examine and create bad sectors— but to do sol need to know what one is. What makes them different to ordinary sectors and how are they created? I

As far

as the DLI part of your quesgoes, the answer is probably a slip up on the part of the authors of Dos 2.5. When the ramdisc is accessed various portions of rom and ram are switched in and out of the memory map, and the operating system must before always be deactivated attempting to do such bank selection

tion

operations. This involves turning off both the Vertical Blank and Display List Interrupts (VBIs and DLIs) by setting location 54286 to zero. Normally the

original contents would be stored temporarily on the stack, but in this case that doesn’t seem to happen and the value 192 is restored after the Dos call re-activating any DLIs as well as the required VBI system. The other part ofyourletter requires a greater understanding of the way in which an Atari disc drive works. Although we tend to think of disc sectors as being numbered sequentiaIIy from to 720, the disc drive actually sees them rather differently. lt deals with the disc as 40 separate tracks with each containing 18 sectors of data (or 26 if you're using an

reading each sector in turn until it finds one with a header value of one. As soon as it finds the correct

and 18 so

header it knows that it must send the next 128 bytes of data directly to your micro. Finally, all the data bytes are added together and compared with the original checksum digit found in the header, and only if the two numbers match will the transfer be considered complete. The drive expects there to be 18 individual sectors, each with a unique number, but it is theoretically possible to have more than one sector with the same referencenumber— it being pot luck which one the drive arrives at first. Some discs even contain 18 sectors, all with the same number —

when you ask to read a given disc sector, the number you specify must first be converted into track and sector references and only when the disc

giving 18 possible sets of data for one official sector number. There are obviously some devious ways of contriving to read a specific

—

enhanced density disc). Each sector within a track is assigned a

number between

drive's read/write

head is positioned over the correct track can the sector offset value be used to read in the

correct data. For example, if you try to access sector 18 the drive looks on track 0 for the sector numbered 18. Similarly, sector 19 would actually be at track 1/sector 1 and so on up to sector 720 which is really track 40/sector 18.

Some manufacturers use a special timing hole punched into all 5.25in discs to work out where each sector occurs within a track. Atari, however, opted for a software approach and each sector has a short block of header data which provides the sector

reference

number and some error prevention checksum data. What you have come across is a method of copy protection used by some disc manufacturers. As you have observed, the first directory entry is located at sector number 361, which is in fact the first sector of track 20. Whenever you ask for a directory (from sector 361) the drive head moves straight to track 20 and starts

a disc like

this with

ment to make such discs, and the program won’t run unless this custom format is present. The same applies to so-called bad sectors, which are often physically

damaged or given incorrect checksum thus returning a disc read digits error even when there may be 128 bytes of good data present. Once —

again, you can’t create these with a normal drive indeed Atari has provided you with an awful lot of circuitry to prevent the possibility of any bad data being recordedonadisc. Of course, you are a responsible Atari owner, and wouldn’t be inter— ested in actually copying such things anyway, would you? That would be both illegal and immoral, and is the —

write your new defaults file on to your work disc, and not used the original version on the master disc at all. As you have discovered, your master is now corrupted and you should send it back for a replacement(although you will probably have to pay the media cost somewhere around £3 to E5 sounds reasonable). The first three boot files on the disc were originally hidden from view by

from my modified Dos 2.9, and now the defaults file seems to contain some 800 sectors — but the disc still doesn’t boot. / hope that you can offer me a so/— ution as to how to get SuperScript working again, or print a warning in your magazine for other readers so it won’t happen to anyone else.

entries, so when you tried to write a new file on to the disc the first blank entry was assumed to be empty and re—used, thus corrupting the hidden DOS.SYS file.

After all, you’ve paid out your £50 and the pro-

August I bought the Super— Script wordprocessor which/had seen advertised in Atari User, and which lam generally very happy with. However, a few days ago I was rereading your March 1986 issue containing the SuperScript review in which the reviewer mentions a bug

the Epson printer driver and changed the Return number 13 to 155. Then I used the Document Rep/ace option to write the printer driver back to my disc and put the program away. The following day I tried to boot SuperScript and I could only get the READYprompt or the Self—Test menu. Upon checking the disc I found that the first three files, the ones with hearts in the directory, had been

with the Return character (13) versus the normal Atari code of 155. As I had already encountered the problem ofprinting a text file to disc! was glad to get an answer to this problem, so I decided to follow the reviewer’s advice and alter the 13 on my work disc defaults file, and in the Epson file on the master disc. [booted up SuperScript and loaded

As you have by now realised, it’s always a mistake to write anything to a master disc unless you’ve first made a backup of it. Since SuperScript is heavily copy-protected, it’s best to that you just don’t write assume anything to it at all. What you should have done is to

will then erase the background at that position. When the time comes to move it, we re-print the original background data, which erases the moving character and restores the background—all in one go. Although it sounds fairly simple, it’s a very complicated thing for a computer to do. Consider this statement:

month, it's quite easy keyboard character move around the screen by just printing a blank space over it. then T's-printing it somewhere else. This is fine as long as the background is blank, but suppose the character has to move across aterrain map or other scenery? if you print a blank space every time the character moves, it will leave behind it a trail of missing background. The theory behind overcoming the problem is straightfowvard: We first look to see where our moving character is about to land, ?nd what's cur— rently printed there and store the information in a safe place. Next we print our character, which

name you choose.

Here's how it works in practice, using the ball Ascii 20 as our moving character. We’ll let the ball's current position be H1, V1 and its new position H2,V2. Also, for convenience, let's pretend the values for H2 and V2 are updated by an imaginary subroutine at line 1000. Our pro 9 ram might look like this: —

a. Line 60 identifies the background character which, is currently sitting at the ball's new destination H2, V2- and stores its Ascii number in O, replacing the previous value. Line 70 prints the ball at H2, V2, and this is where we came in. The whole process will repeat until we stop the program by pressing Break or Reset, or switching power off. Program is a fully working demonstration that's similar to last month’s Program lV, but we’ve rearranged things to give you a bit more practice with subroutines. Notice that the joy-

stick control system — lines 150 to 340 is now nested. The first subroutine (150 to 260) calls other subroutines (270 to 340) as necessary, before

restoring the original background data — the character whose Ascii code is held in

program by telling computer what graphics mode wethe re using. it’s essential to do this, or the LOCATE command won't work. Next we specify the ball's starting position H2, V2, then jump into the middle of the main loop at line 60. This line reads the background character at our ball’s initial position and stores it in 0. Line 70 prints the ball, and line 80 sets H1 and V7 to the ball's current coordinates. Line 90 then sets the game loop running.

of the few languages that doesn't demand an accurate flow chart before you start programming it's very tolerant of variations in construc?on and layout. As your programs become more complicated, however,you’ll find that time spent on designing it by flow chart or other methods will save many hours of trial and error and the end result will be tidier, shorter and probably faster. Now let’s turn to a topic that will help you to produce more realistic games—the use of colour. Deep inside your Atari is a group of memory addresses called colour registers. Whenever the computer draws a screen they tell it which colours to use and what to use them for. You can change the contents of the registers, and consequently the colours displayed by using SETCOLOR. For convenience and to avoid misspelling this command can be abbreviated to SE. Basic will write it out in full when the program is LISTed. its format looks like this. Basic is one

have only one, corresponding to clone.

The first figure after SETCOLOR identifies which register we want to alter. ln Graphics 0 we can use only 1, 2 and 4

The second figure specifies the colour or hue to be used and can have any value from 0 to 15. Figure ll shows the hues available using Atari’s own words, but you may disagree with the descriptions. in any case there's no absolute standard many TVs and computers will inevitably produce different results. The third and final figure in 3 SETCOLOR command controls the colour’s brightness, and it can be any even number from o to 14. Changing this level has a marked effect on the perceived colour. For example:

ONE of the best known

software for the 8 bit

houses producing games Atari is Tynesoft. Based in Blaydon, Tyne&Wear, it is constantly bringing out quality new software to add to its

‘

25;

already impressive range. So it was with eager anticipation that went to have a chat with David Croft, Tynesoft’s head of software development. The main topic of conversation was the development of its new sports simulation. Said Croft: “We were determined Winter Olympiad ’88 would surpass all other sports simuIations in terms of realism, playability and visual presentation". He said this was Tynesoft’s most ambitious project to date, with versions being produced across as many computer formats as possible. To make this possible all other inhouse work was halted and programmers, graphic artists and freelance people alike got together to decide the game’s format. The first step towards creating it was to spend lots of time watching videos of winter sports and deciding which events would appear. They eventually settled for the downhill, bob sleigh, ski jump, slalom and biathlon.
