tanks which you control from a plane above. Deep in enemy territory, your mission is to use the tanks to ex plore and map the area.

While mapping a narrow canyon, you are taken by sur prise by an enemy task force. Designed specifically to

combat robot tanks, the task force consists of waves of mines which detonate instantly upon contact. Further

more, low-flying enemy planes which move methodically back and forth across the canyon will bomb any tank they happen to fly over. Your task in Mine Canyon is to keep your tanks alive as long as possible by steering them through the gaps

Once the program has loaded, type SYS 49152 to start it. To play Mine Canyon, a joystick must be plugged into Port 2. When you've started the game, youli nolice that the view of ihe canyon is from above. You can move your tank north, south, east, or west. When your current tank is destroyed by a mine or plane, your next tank will come into play, until all four tanks are gone. You score 10 points each time a new row of mines moves into view. When all your tanks have been destroyed, the final screen which contains your score will appear. Theoretically, the score can go

this is optimistic to say the least; you're doing well if you can score 2000 points. When the final screen appears, you can play another game by pressing the joy

There are two ways to maximize your score while playing Mine Canyon. The first and most obvious way is to avoid moving your tank to the extreme north or south of the canyon (top or bottom

of the screen) when possible. You can also maximize your score by biding your time. Wait until the enemy plane is al most on top of the tank, dien quickly

'he graphics tools on the Commodore 128 en courage sophisticated exploration. Drawing straight-edge figures on the screen is relatively easy with the DRAW command. Combining text and graphics is cumbersome but not difficult with the CHAR command. What more could we want? Two things: viewports and windows, These are essential pans of every graphics toolbox.

Viewports specify where on the screen to place the im age. Windows allow the image to be scaled up or down within ihc viewport. The Mocbius (or Mobius) strip is merely a topological curiosity which we will use as an interesting figure to illustrate the effects of viewports and windows. (As an aside, you can contruct a Moebius strip from

a long, narrow strip of paper. Tape or glue its ends to gether, but give one end a half twist before doing so. You now have a single-sided object, believe it or not. If you are skeptical, try painting one side one color and

ihe other side another color. One color is all it lakes! Another surprising property of this seemingly simple loop is that you may cut it lengthwise down the middle and still end up with one loop, not two.) Moebius strips are not really our concern. We are in terested in the enhanced capabilities provided by view ports and windows. We saw last month that only certain

functions could be readily graphed. The graphs of most functions are too large or small to 111 nicely on the screen. A standard solution to ihis problem is lo perform a

windowing transformation of the points on the graph be fore displaying them. Here is an important note before we begin: The windows we will discuss arc not to be confused with the BASIC 7.0 WINDOW command, which actually deals with a text viewport. Think of ihe window as the sheet of graph paper on which ihe origin al function is plotted. The size of the paper and the scales on the axes determine the size of the graph. For example, consider drawing a 2 mile by 2 mile square to scale on graph paper. Assume the sheet of graph paper has 100 horizontal lines and I(X) vertical lines. If you assign a scale such that one line (or grid! equals one

mile, ihe graph will be a tiny square two units on a side.

tf you decide thai every ten grid lines represents one mile.

now the graph will be a square twenty units on a side and will 1111 more of the paper. Change the scale so that

fifty grid lines equals one mile, and the graph of the square completely fills the paper.

With ihc windowing transformation, we can specify the number of units horizontally and vertically on the graph paper. If we say that the entire graph paper is four

units wide and two units tall, the two-by-two square fills the paper vertically and is half its width. 20

AHOY!

WORLD COORDINATES We use the â&#x2013; 'world coordinate system" to specify the size of ihe window. World coordinates are to be distin guished from "screen coordinates" which we will discuss

later. Let's assign to the left and right sides of the win dow the values 0 and 4. and to the bottom and top we give 0 and 2. The four corners of this window have coor dinates (0.0). (0,2). (4.2). and (4.0). starting at the lower

WT 0&LÂŁ KlWEfTf left corner and moving clockwise. The first value of each coordinate pair represents the horizontal location, and the second value of the pair indicates ihe vertical loca tion. The window and the coordinates of its corners are

represented in Figure 1 (see page 24). Now we may draw the graph of a two-by-two square in this window. If the lower left corner of the two-by-

two square is at coordinate (0.0). the graph of the square

will fill the left half of the window. II" we change the co

ordinates of the window so its lower left corner is (-2.0) and its upper right comer is (2,2), the two-by-two square

starting at (0.0) fills the right half of the window. Now redefine the window so that it goes from -4 to 4 horizontally and from -2 to 2 vertically. The two-bytwo square starling at (0.0) is represented in Figure 2 (see page 24). AHOY!

so that it is easily understandable and adaptable. Line 10 saves the current screen mode. Line 130 re stores that mode when the program is finished. The high

resolution graphics screen is specified and cleared by line 20. The initialization subroutine beginning at line 500 uses the specified window and viewport coordinates to calculate conversion constants A, B, C, and D beginning at line 650. (0,2)

Figure li World Coordinates

The world coordinates of the window are stored in WL,

WR, WT, and WB starting at line 520. These correspond to the left, right, top, and bottom values of the window. The screen coordinates for the viewport are given by VL, VR, VT, and VB starting at line 590, also correspond

from their world coordinate values to screen coordinates. The subroutine at line 2000 which is called by line 50 performs the conversion. The scale factors are applied to the X and Y coordin ates in lines 2010 and 2020, giving screen coordinates XS and YS. Before these points are plotted, the subrou tine at line 3000 is called to eliminate any points which

are outside the range of the viewport. The C-128 is very unforgiving if asked to plot a point which is off the screen. Line 80 flips the YS coordinates upside down to match the physical screen coordinate system. The subroutine at 4000 or 5000 is called to move to the point (XP.YP) or to draw a line from the previous point to that point. The main program loop is repeated from line 40 until all points have been used. Finally line 120 paints one side of the figure, and line 130 restores the original screen mode. If you use a single screen for text and graphics, you might add this statement: 125 GETKEY A$

ing to left, right, top, and bottom. Remember that VL and VR must be between 0 and

320 {0 and 160 for multicolor graphics), and that VT and VB must be between 0 and 200 since those are the pixel limits on the high resolution screen. Remember also that both coordinate systems assume that up and right are positive directions while down and left are negative.

This will retain the graphics screen until you press any key to return to the text screen. [320,200]

(IB,130)

(200,130)

The point (0,0) is assumed to be in the lower left comer

of the screen. Line 700 draws a box on die screen to represent the

location of the viewport. Notice that all Y-values to be drawn or referenced must first tic subtracted from 200. This allows the screen to use "normal" coordinates with 0 at the bottom and 200 at the top. (4,2)

Figure It Redefined Window Coordinates The next subroutine called by the main program be gins at line 1000. The X,Y pairs of coordinates for the Moebius strip are in DATA statements beginning at line 1100. If the X coordinate is negative, this program as sumes that the graphics cursor should move to that point

rather than connect it with a line to the previous point. The values of 1E29 in line 1140 tell the program that the last point of the figure has been accessed.

The variable MV is returned to the main program to show whether to quit (MV=1), move to the current point (MV=2), or draw a line to the current point (MV=3).

Before any points can be plotted, they must be converted 24

graphics commands should allow negative relative coor dinates (according to the C-128 System Guide), my ma chine does not accept them. For example, PAINT 1,-2, +3 should start painting at a point which is 2 units to the left and 3 units below the previously accessed point. Unfortunately, my C-128 gives an ?Illegal Quantity Er ror message for the negative value. The RDOT function easily overcomes the problem. RDOT(0) and RDOT(l) represent the last X and Y coor dinates referenced. It is a simple matter to add to or sub tract from the RDOT values to create relative moves as line 120 shows. The statement PAINT l,RDOT(0)-2, RDOT(l) is equivalent to PAINT 1,-2,-H). That is, move horizontally two pixels to the left to begin painting. To better appreciate the power of the these graphics

tools, experiment with different values for the window and for the viewport. As a start, run the program as listed. Next change the values in lines 590 through 620 to 125, 185, 140, and 100 respectively. Then type RUN 30. The original image remains on the screen if we skip line 20. Now the viewport is much smaller than the original one.

Note that the new image is smaller but still centered with in the viewport just as the original is.

FUNCTIONAL GRAPHICS

For plotting the graph of a function, DATA statements are not needed. The program Function Plotter on page 92 allows you to define a function in line 530 and to plot its graph. The viewport is specified as before in lines

640 through 670. The left and right world coordinates of the window now correspond to the domain (X values) of the function to be plotted. The range of Y values is calculated and displayed by lines 120 and 130. If the graph does not fit within the viewport, change the values of the window's WT and WB to match Y MAX and Y MIN and run the program again. Add line 155 GETKEY A$ if you're using a single monitor for text and graphics,

the NoScroil key will allow you to temporarily stop the plotting, if desired. Change the step size of the X values in line 550 to make the graph denser or sparser, These programs are the groundwork for some high-

powered graphics work. The primary tool needed to complete this graphics package is a clipping routine. The limiting routine at line 3000 will distort any figure in the Moebius Plotter which goes outside of the window boundaries. Make sure that the window is large enough lo include the entire figure. Putting graphs and graphics exactly where you want them has never been easier. Enough words. On with the pictures. □

But it certainly complicates the job of the programmer working in hi-res graphics, since it eliminates the possi bility of using straight X/Y coordinates to plot dots on a high resolution screen. Instead, the relationship between each dot on the screen and its corresponding bit in screen RAM must be painstakingly calculated, using what must be one of the most complicated algorithms in the world of hi-res graphics programming.

HOW IT WORKS To illustrate how this complex algorithm works, let's go ahead and devise a system of coordinates for a 320 dot by 200 dot hi-res screen, using the letter X to repre sent each of the 320 dots going across the screen and the letter Y to represent each of the 200 dots (or bytes) extending from the top of the screen to the bottom. This arrangement is illustrated in Figure 2.

As Figure 2 shows, there are 320 possible X coordin ates on a hi-res screen, ranging from 0 to 319. And there are 200 possible Y coordinates, ranging from 0 to 199. So an X coordinate and a Y coordinate, used together, can be used to plot any dot on the screen. But, since the screen is actually divided into 1000 matrices of 64 dots each, some kind ot"conversion formula must be de

vised if these screen X and Y coordinates are to be of any help at all in accessing data in screen RAM. Actually, the algorithm that is most often used for con verting C-128 coordinates into screen memory addresses is made up of several parts: First, since each rectangle on the screen is eight dots wide by eight dots high, both the X coordinate and the Y coordinate must be divided by eight. So, if we use the variable ROW to represent the starting address of a

horizontal eight byte row of dots, and the variable COL to represent the starting address of an eight byte column of dots, we could start our algorithm with these two equa tions:

ROW = INT(Y/8)

and

COL = INT(X/8)

Next, since each horizontal row of dots is made up

of eight horizontal lines, we could number those lines 0 through 7 and find the line number of the dot in ques-

tion by using this equation:

changed with a statement such as this:

LINE = Y

POKE BYTE.PEEK(BYTE) OR 2

AND 7

Another odd quirk about the C-128 screen is that it displays the eight bits in each byte of screen RAM in the opposite direction from the direction in which they are stored in memory-with bit 0 on the left of each byte

shown on the screen, and bit 7 on the right. So an equa

In order to plot a dot on a high resolution screen, it is also necessary to understand the use of the C-128*s color map, which begins at memory address S1C00 (7168 in decimal notation). The C-128 color map contains 1000 bytes, each of which determines the color of one eight

determined, the base address of screen RAM can be

added into (he equation, and the sum should be the ad dress of Ihe byte in which the bit in question is situated.

So now let's put all of the above formulas together and add them to the base address of the C-128's screen mem ory. We could do that with a formula like this:

BYTE = ROW * 320 + COL * 8 + LINE + BASE

Because of the limitations of this system, the C-128 does not offer the programmer as much control over set

ting screen colors as it does over whether individual dots on the screen are off or on; only two colors are avail able in each eight dot by eight dot (character size) ma trix, and each dot in that matrix must be displayed in one of those two colors. However, there is no overall re

striction on how many of the C-128's 16 colors can be displayed on the screen.

Finally, once the RAM address of a byte has been cal culated, Ihe state of any given bit in that byte can be THE LOWEST

You should now hear your digitized voice emanating from the monitor's speak er. The reproduced speech will have a raspy, buzzing quality similar to that of a CB radio, but it should be quite intelligible. You should speak slowly and articulate your words to get the best results when recording your voice on tape.

At this point you may save the digital speech data us ing option 4 from the menu. Note that this is the digi tized speech data, and not the original voice signal you recorded onto cassette earlier. By saving this digital data, you can use it later in your BASIC programs. The default device is the disk drive, but you may save to cassette by

will need a cassette recorder and Datasette for digitizing your speech, but you need no extra hardware for play back. Your recorded voice is reproduced in the standard audio output of any Commodore 64. Before we get started, here is a quick overview of what we are going to do. First you will record your voice onto a cassette (ape using any cassette tape recorder. Next you will piacc this tape into the Datasette connected to your Commodore 64. Please note that it is a tape recording of a voice and not a computer program that is loaded into the Datasette. Finally, you will run the Speech64 pro gram, which will record the speech from the Datasette. You will then be able to play back and save the speech data. The point here is that we are not using the Data sette to load or save programs (unless you do not have a disk drive), but only as a means to input the speech signal. Let's get started. Type in the Speech64 program on page 103 and save it. Now, using a standard cassette re corder, record a short phrase (under 8 seconds). If you are using a recorder with a built-in microphone, use a

plug-in mike instead of the built-in one. The reason is that the built-in microphones tend to pick up too much noise, and your voice will sound very thin on the com

Players take turns trying to match blocks. To select a block, move the joystick until the cursor is positioned on the block you desire. Pressing the fire button selects the block and exposes the picture that the block contains.

TWO BLOCK VERSION In this version, a match equals two identical blocks. When this occurs the MATCH in the title Slashes and the computer plays the 'CHARGE' theme. The player's score is increased by one and the player gets another turn.

DOGCATGHER For the C-64 By Bob Blackmer

ogcatcher is a colorful arcade game for the Commodore 64, written entirely in machine

language. The characters in this game are a pack of

pesky canines with shiny white teeth and Dash Dolittle, the dogcatcher. Dash also drives a truck to advance to the next level.

When the game starts, the truck backs in and Dash appears behind the truck. He is safe from the dogs at

this point; as everyone knows, a dog would never run down a street with the dogcatchcrs truck on it!

The idea behind the game is to dash around the neigh borhood streets capturing dogs and taking them to your truck and advancing to the next neighborhood, where

the pace of the dogs will be faster. You'll siart out wilh nine lives (pun intended), and will receive 100 points for each dog put in the truck. On the right side of the screen is displayed the game information: score, dogs captured, level, and lives left.

To catch a dog you must be facing him. and at the right moment press the fire button to throw down your net.

You cannot run a dog down from behind to catch it. If you press the fire button loo early, you might not be able

to get your net down again last enough to avoid being bitten.

If you are successful at capturing a dog, the dogcatch er "freezes" with a dog in his net. He will be facing the right side of the screen so he can deposit (he dog in the truck.

At any other time a dog comes in contact with Dash, Dash is bitten, loses a life, and is sent back to the truck. You must be careful after catching a dog to make your way back to the truck without any contact with a dog.

To put a dog in [he truck, jusl touch your net to the back of the truck. You are then ready to get another dog. Af ter catching and depositing the last dog in the truck, it

drives off filled with dogs to take to the pound. The em pty truck then drives back onto the screen and Dash can then clear another neighborhood of runaway dogs. Rather than incorporate sound effects for the dogs and dogcatcher, I oplcd for a musical soundtrack which plays

in the background of the game (I'm sure you'll recognize

the tune).

I'll give you one tip, which will help on the later lev els when the dogs' pace is quick. As Dash runs back and forth across the screen, you'll notice the different shapes that make up Dash. The best position to be in is when his legs are straight, giving you more room to catch the dog before he can bite your leg. Dogcatcher must be entered using Flankspeed (see page 89). After typing Dogcatcher in and saving it to disk, reset the computer and LOAD "DOGCATCHER",8,1. Type SYS 49152 to start. □ SEE PROGRAM LISTING ON PAGE 96

C-64 side of things. It is worth noting that the Apple disk operating system (DOS) must be loaded from disk into 12 kilobytes of the system's RAM. The task of con trolling the drives falls to the 6502 microprocessor in the computer. By comparison, the Commodore disk drives have their DOS in ROM and their own 6502 microprocessor. The C-64 merely issues instructions to the drive which then takes virtually in dependent action. The second most obvious piece of territory on the BUSS Card is die col lection of no fewer than three C-64 cartridge connectors at the front right corner of the board.

and gadgetry to gladden the hearts of many a hacker. The system is clear ly designed with a totally open archi tecture. In this regard we are eager

the first copy we received was a pre liminary version not fit for public consumption. To prove his point he sent a second copy of Super Kit which cleared up all the aforemen tioned problems. We also encoun tered a glitch in the file copier while doing all files in Super DOS mode.

Some of the resulting files were not properly matched to their file names.

Copying a selection of files less than the entire disk worked fine. Super Kit obviously does some strange and terrible things with the 1541 DOS. This apparently makes it sensitive to some of the DOS versions of the past as well as the future. Alignment of your disk drive, as well as its .speed and internal timing, may also prove critical.

bit about it as a programming language. We took a look at the structured nature of Pascal and found that it is much less forgiving about format and structure than BASIC is. And we found that it has more complicated data and programming struc tures. The CASE. WHILE, and extended FOR/NEXT and IF/THEN structures give Pascal more flexibility than

C-64 BASIC. This month we'll try a similar exercise with COMAL. But First let's find oui something about COMAL.

COMAL was designed by Borge R. Christensen and Benedict Loefstedt in 1973 as a replacement for BASIC on the C-64. While it has many of the statements we're all familiar with from BASIC, other more Pascallikc com

ments as BASIC, it goes farther by adding options to some of them. For instance, the IF/THEN statement can have ELSE and ELIF (else if) options. PRINT is expanded to include PRINT USING. Of course, BASIC 7.0 on the 128 has PRINT USING and ELSE.

Rather than try to cover all the differences here in the article's text, I have included tables on the following pages that show the commands available to BASIC 2.0, BASIC 7.0, and COMAL. Because Pascal is not as standardized as the BASICs and COMAL, I didn't include it in the table. Instead, a separate table shows some common Pas cal keywords and their COMAL equivalents. A quick look at the table will show the commands that

cal's CASE, PROC, REPEAT, and WHILE. These function similarly to their Pascal counterparts in most re spects.

You should know that COMAL's GOTO doesn't use line numbers. Line

numbers are used while program ming, but the GOTO command ac

cesses routines by name. As with Pas cal, functions and procedures are giv en names and can be accessed by calls to those names. There is no GOSUB command in COMAL. COMAL includes an EXEC com

mand to "execute" procedures, but it isn't necessary most of the time. To use a procedure or function, you merely type its name on a line. If you

need to pass any parameters, these follow the routine name.

STRUCTURING As mentioned earlier, your pro grams can be very structured or a bit slapdash. There arc a few necessities. String variables must be defined (i.e.,

This problem was submitted by Bill Okerblom (Provi dence, Rl). Generate a list of all possible one- and twocharacter floating-point variable names. The first char acter must be a letter, and the second character must be a letter or a number. To make this very easy, your pro gram may list the two-character reserved words (FN, GO,

IF. etc.) as well.

Steven Sleekier (Columbia, MD) suggested this chal lenge. The user inputs a sentence or phrase. The com puter responds with a list of the words in a column. Fol lowing each word is its character count. The character

count column is totaled at the bottom. For example, if the user enters "COMMODARES ARE FUN," the com puter output is

PRINT A$

David Alan Wright (New Britain, CT) wroie his pro gram to avoid the use of IF statements. Mike Stype (Mich igan City, IN) replaces any used digits with an "X". The program from Karen Middaugh (San Diego, CA) com pares each selected digit with the previously selected ones to eliminate duplicates. David Hoffner (Brooklyn, NY) uses the Z array to keep track of selected digits. Each digit is a subscript of the array. When a digit is chosen,

The COMAL statement PICK$

:= PICK$(2:LEN(PICK$))

is equivalent to the BASIC statement

PICK$ - MID${PICK$,2) In other words, starting with the second character, take all characters up to the end of the string. Line 220 in Henry's program is comparable to the first statement in line 30 of David's program. Each of these lines forms

a new string by taking all characters to the left of the chosen character plus all the characters of the right of the chosen character. The length of the string i,s thereby reduced by one. Among the solutions for Problem H29-3: Beat Keeper

is the following program from Bill Okerblom (Provi dence, RI):

the corresponding element of the array is set to one.

The COMAL solution for selecting four unequal digits from Henry Farkas (Elklon, MD) is listed below.

Bob used the fact that one number must contain four dig

ematical proof of that fact. Bob's program tests only 126

products. He knew that the digits in each factor must be in descending order, and his program always places the shorter of the two factors first in order to avoid testing

The problem requested a simple, adjustable metronome

simulation with sound, graphics, and the speed in beats per minute displayed. With Bill's program, press the "+" key once while the program is running, and the speed increases until you press the "0" key. The "-" key re duces the speed the same way. It even sounds like one

of those expensive metronomes. Thanks to Jim Speers (Niles, MI), who used a similar graphics display, lo Matt Shapiro (Ft. Lee, NJ), who dis played "TIC ... TOC" in the true spirit of "simplest is best," and to Mike Stype (Michigan City, IN). Thanks also to Barry King (Nome, AK) for suggesting this Commodare.

Problem §29-4: Large Product brought a wide range of solutions. One from Wallace Leeker (Lemay, MO) took nine hours to run. Wallace used Allan Flippin's permu tation routine from the April issue to generate all possi ble pairs of numbers with no duplicated digits until he found that 9642 * 87531 is the right combination to give the maximum product, namely 843.973,902. At the other extreme is the program below from Bob

each pair of factors twice.

Jim Spccrs (Niles, MI) concluded that the factors must be one four-digit and one ilvc-digit number. He proved this by multiplying one 9 by eight 9's, two 9's by seven 9's, and so forth. The largest product was from four 9's times five 9's.

Thanks to Matt Shapiro (Ft. Lee, NJ) and Bill Hoyt (Battle Creek, MI) for their solutions and explanations to this problem.

Congratulations also to Stephan Fassbender (Saarbruecken. Federal Republic of Germany-sorry I confused your street address with your city last time), Vincent Lui, Mi chael Loiodice (Herkimer, NY), Necah Buyukdura (An

kara, Turkey). Don Wynkoop (Torrejon AB. Spain), Ed ward Oros. Jacquelin Catlaway (Orange Beach, AL), John A. Haksch (Richmond, VA), Paul Sobolik (Pittsburgh. PA), Peter M. Landers, Dale Zwicker (Canada), and Lawrence Berlinski (Linden, NJ) for all your programs and explanations. Looking forward to seeing more of your solutions and

problems in next month's installment of Commodores. Keep those keyboards busy. □

DYNAMIC 128 The dynamic keyboard is a popular technique that al lows modifications of a BASIC program while it is run ning. Since there have been numerous articles on this subject, I won't elaborate here. However, the appropriate addresses for the C-128 are not readily available. The cor

Here is a short routine which will take the hassle out of deleting multiple lines from a BASIC program. To use the routine simply insert the appropriate first line num ber minus the increment (line 60000), the increment it self (line 60001), and the last line number plus the in crement (line 60002). An increment of one will delete all lines between the first and last line number.

The routine is best used by appending it to the end

rect procedure and addresses are provided here: 1. Onscreen, print the lines to be added to the BASIC program. Print no spaces between the BASIC lines.

2. Define any needed variables with lines like A = 100. Print a GOTO < LINE NUMBER > to restart the pro gram. Allow three spaces between each of these lines. 3. Sequentially POKE the keyboard buffer at 842 with a RETURN (the number 13) once for each line printed on the screen.

4. POKE 208 with the number of characters in the key board buffer.

5. Position the cursor over the first line printed on the screen and end the program. A program is worth a thousand words, so I have writ ten a demonstration program, Dynamic 128. As the pro gram shows, the only difficulty with the dynamic key board is properly spacing the printed lines. The program AHOY!

VARIABLE MANAGER For the C-128

By R. Harold Dreid 'nrinhlc Manager nflcis two additional com"wnds for your \2\i: a FIND rl"") command and a CHANGE ("C") command. FIND prints out the line numbers where a variable is referenced within a program. It's useful for de bugging; it's also a convenient way to check a variable name for uniqueness before you use it. CHANGE lets you change variable names. If you "re in the habit of using long, descriptive variable names in your programs, use the C command to turn them into short, efficient ones.

Many BASIC enhancement packages include these fea tures, but Commodore left them out of BASIC 7.0 on

the 128. Install them at the start of a programming ses sion, and they can save you a lot of tiresome, repetitive editing.

Variable Manager occupies four blocks of memory,

it's moving the BASIC program around to make room for longer names, or condensing to allow for shorter ones.

Variable Manager scans BASIC, finds all the variables, and compares each with the name you're finding or changing. It's smart enough to recognize that numeric, string, and array variables of the same name are distinct from one another. But it's not smart enough to know that it's been asked to replace a valid variable name with an

invalid one, or a string variable with a simple array. So be careful with the CHANGE command. Be certain that the variable types agree, and that the new name is valid. Look twice before you press RETURN when using the @C command. It's probably a good idea to SAVE first,

just to keep a finger slip from having unwelcome results. By way of example, these CHANGE statements work correctly:

at addresses S1800-S1BFF (decimal 6144-6911). It wedges

into BASIC by taking over the CRUNCH vector at $304$305 (decimal 772-773; this vector points to the routine that converts BASIC keywords into tokens). The program listed on page 113 is a BASIC loader that puts Variable

@CVALUE%(,V%(

Manager into memory; it POKEs the code into place, enables the wedge, and then wipes itself out with a NEW command. So be sure to save a copy before you run the

These statements, however, can lead you into real trouble:

@CA$(,ANY$

To save space, the syntax for the Variable Manager commands is simple, and a little unforgiving. Use the

Follow F with a variable name. Follow C with the vari able name to be replaced, a comma, and the variable

When switching to longer variable names, be sure you don't push your lines beyond the 160 character limit. A lot of programs grow to an unmanageable size be cause there are too many variables doing too many things. Variable Manager helps you keep track of them. Apply

BUG REPELLENT By MICHAEL KLEINERT and DAVID BARRON Bug Repellent is a checksum program used for proofreading BASIC liilings typed in from Ahoy! magazine. For each program line you enter, Bug Repellent Will produce a two-letter code thai should match the code listed beside that line in the magazine.

Type in, save, and run the Bug Repelltitf. (If you have u C-M, type in the C-6J version. If you have a C-128. you will need to type in ihe C-64 version fur use with C-64 programs, and the C-I2H version for use with C-I2K programs,) If you have typed in Bug Repellent properly, you will gel the message BUG REPELLENT INSTALLED; otherwise you will gel an error message. If you gel an error message, double check llic Bug Repellent program for typing mis

takes. Type NEW and hil RETURN. Then lype in and save, or load, the Moyl program vou wish to check. Type in SYS 49152 for the C-64 version or SYS 3072 for the C-128 version and hil RETURN (this will begin execution of Bug Repellent), You will see ihc prompt SCREEN OR PRINTER '.' Hit S if you want ihe codes listed on ihe screen, or P if you want them listed on the printer To pause Ihe listing depress and hold the SHIFT key.

Compare the codes your machine generates to those listed to the right of the corresponding program lines. If you spot a difference, that line contains an error. Write down the numbers of the lines where the contradictions occur. LIST each line, locale the errors, and correct them.
