If you own a C-64, you The one you purchased. And the GEOS realizes the technical potential that has been in the C-64 all along. Speed. Power. Ease of use. Sophisti cation. Elegant, practical

applications you might expect of a high-end personal computer, all made possible with GEOS. It's so simple— but then, so was fire. Once it caught on. To begin at the beginning. GEOS stands for GRAPHIC ENVIRONMENT OPERATING SYSTEM. Why? GRAPHIC: Because menus and icons replace long, typed command lines. Point and click, that's it.

GEOS can be divided into 4 areas: two functional aspects (deskTop and Desk Accessories), and two major applications (geoPaint and geoWrite). deskTop. deskTop is a graphic interface, making file organization and manage ment easy. As always, you call the shots. Load a disk. 1 Files appear as icons on the disk notepad; to flip through, point at the folded corner and click. Prefer a file appear on a different sheet? Move it. It's easy.

ENVIRONMENT: Because GEOS provides a consistent, powerful way to use your computer. Learning new applications is a

snap (or should we say click).

OPERATING SYSTEM: Because GEOS orchestrates every function so that they all work together systematically,

even symphonically. Some basics. Icons are graphic images which represent files or utilities. Each is different, and all are easy to recognize and easy to use.

A menu is just that: a list of functions availa ble for selection. When a menu appears,

move the pointer to any item you wish. Click. Click. You're on your way.

A pointer is used to select and activate items. To move the pointer, roll the mouse or trackball or rotate the joystick. Once on target, click once to select; click a second time to activate. Fonts are a new way of looking at text. Choose from 5 different fonts (with more on the way). Try Stoinclle, or Roma, bold, or italics, even underline and . Need to fit more words on a line? Pick a smaller point size, like umvemtyspoM, and get over one hundred characters per line.

All this and fast too. Because the integrated diskTurbo software improves 1541 disk drive performance 5 to 7 times. That's right. On both reads and writes.

Create a new document or re-name an

existing one. Want to copy a file onto the same or a different disk? Fine. Forgotten what a file contains? Select "get info" from the file menu. A description of that file's contents appears. Finished with a file? Print it. Save it. Or drop it in the trash and have done with it. Your call. geoPaint. A full-featured, color graphics workshop at your fingertips. The pointer operates any one of the fourteen graphic tools and shapes in the drawing menu. Create masterpieces on the Drawing Window. By turns, use a pencil, an airbrush or a paint brush, each with a character all its own. Draw straight lines, squares, rectang les or circles. Fill in with any of the 32

patterns. Switch to pixel-mode, where each

dot in a selected section is magnified many times its size for easy manipulation.

Add text if you like, in different fonts, styles or point sizes. Even change its position or layout at will.

Move or copy any part of your creation. Once done, you can include your artwork in another document—a letter home perhaps. (Won't Mother be pleased?) GEOS makes it easy.

I=W FROM 71-11= If the Ahoy! Disk gets

any better, we'll have to sub scribe ourselves.. .and we get it for free! These past four months, we've shipped nearly full, with programs provided by the COMAL Users Group occupying the space left over by our monthly lineup. This month, we've given COMAL a rest to provide another exciting commercial program. The Talking Disk from Covox is more than a demo of their $89.95 Voice Master: its several programs are entertaining and educational in their own right. As de tailed in the August Scuttlebutt, the $5.00 disk includes a talking keyboard, a calculator that converses in English, Spanish, and German, and instructions for creating voice synthesized programs. Because of the software's total length—over 400 blocks—we've had to double-side the Ahoy! Disk to fit it all in. But despite that, and the in clusion of a 28-page manual, the October disk costs the usual $7.95 (see page 54). Believe us: they're not giving it away simply because

With a joystick plugged into Port 2, you can move the penguin in all directions as long as he is standing on one of the three snowbanks. When he is in the water, how ever, he will coast forward unless you pull back on the stick to bring him to a dead stop. There are safe ice floes at intermittent intervals be tween the killer whales, and when you are touching one you will stop coasting. It is possible for you to cling to one of these until you pass close enough to a cavern to swim off. Score is determined by the green bar just below the ice caverns. It gradually turns red from right to left, show ing you how much bonus score is left before time runs out. When time runs out, you receive no bonus score upon entering one of the caverns. Bonus score varies from 100 points to 3900 points, de pending on how long it takes you to get across the screen to the safety of the caves. When you enter an ice cave, you must avoid the razorsharp icicles on either side of the entry walls to get in side safely. If you enter a cave touching one of the ici cles, or there is a polar bear inside when you enter, your little penguin will sprout angel wings and float off the screen.

If you enter safely, a victory fanfare plays, the pen guin jumps for joy, and a new penguin is positioned at the bottom of the screen. Each time you enter a cave safe ly, the game picks up the speed a little. You have three penguins per game, denoted by the three check marks on the bar at the bottom of the screen. To start a new game, hit fl. My high score so far is 24000+. It gets pretty hard after about eight penguins, because the wolverine and the killer whales really start hustling. The interrupt divides the screen into three different col ors, moves the three separate groups of killer whales, and propels the wolverine along the snowbank, along with updating the musical theme. I hope you take the time to type in Penguins—it is a nice inexpensive addition to your game library. Since the game is entirely in ML, you will need Fkmkspeed to type it in. □ SEE PROGRAM LISTING ON PAGE 110

MOUNTAINEER MACK the C-64 By Stephen Devine ountaineer Mack is a fast-paced moun tain climbing game for one player.

There are three levels of play, with each level having

Each step upward adds five points to your score and 20 to the current elevation. Blue sky will appear at the top of the screen when the peak is near. (The rocks cease to fall at this point.) If Mack collides with an object on the screen, he falls to the bottom. You

A/D (read "A to D") converters each generate an eight-bit

ERT I?I=IÂťCI? anywhere between logic high and logic low levels? Before the computer can read a paddle's position, an analog to dig ital conversion must be performed. The entire range of pad dle resistances is subdivided into 256 equal parts. The A/D converter takes the paddle signal and determines a numer ic value from 0 to 255 which is proportional to its resistance. For example, assume that if the paddle is turned coun

terclockwise, its signal level (or resistance) is low, and when turned completely clockwise, its signal level is high. The A/D converter stores a digital value of 0 in the SID regis ter when the paddle is counterclockwise, and a digital value of 255 when the paddle is completely clockwise. If the pad dle is turned halfway between the two extremes, the A/D converter generates the value 128. The computer can interpret the position of the paddle by the size of this digital value. The paddle's position is deter mined with a resolution of one part out of 256 parts. Con

trast this with the joystick whose position is known with a resolution of only one part out of eight. In electronics

jargon, the SID chip contains two 8-bit A/D converters.

The eight bits make up one byte, and one byte ranges in value from 0 to 255.

INNER WORKINGS

For those interested in the electronic details of how the analog to digital conversion occurs, have a look at the sche matic diagram for the SID chip in the Programmer's Ref erence Guide (page 610 for the C-128 and page 481 for the C-64). The paddles are shown as 470,000 ohm (470 kohm) potentiometers ("pots") coming into the POT X and POT Y inputs of the SID. A 1000 picofarad capacitor is also at each input. One side of the pot goes to +5 volts.

stick switch as being at a logic high (I) or a logic low (0)

The SID chip momentarily brings the top of the external capacitor to ground (0 volts), removing any charge from it. At the same time, it starts an 8-bit binary counter counting fixed-rate pulses. The capacitor then begins charging up through the paddle potentiometer. The smaller the resistance of the pot, the fester the capacitor can charge up. The voltage on the capacitor increases as it charges up. This voltage comes into a circuit in the SID called a com parator. The comparator compares the voltage on the ca pacitor with a fixed voltage which is nominally 2.5 volts. When the voltage on the capacitor reaches a value of 2.5 volts, the output of the comparator changes from a low level to a high level. The high level at its output causes the binary counter to stop counting. The value in the counter will be between 0 and 255, depending upon how long it took the

level. How can a computer read a paddle which may be

capacitor to reach the 2.5 volt level.

The inputs to the A/D converters are accessible through Control Ports 1 and 2 on the right side of the computer. The A/D converters are intended to be used with game pad dles which are plugged into the Control Port connectors. Electronically, a paddle is a variable resistor called a po tentiometer. The value of its electrical resistance may be changed by rotating or sliding the handle of the paddle. The Commodore's A/D converter can handle resistances ranging from zero ohms to about 500,000 ohms. The paddles differ from joysticks on the Commodore computers. The joystick is digital in nature: each of its four

switches is either open or closed. The paddle is an analog device: its output is a continuously variable signal. The computer can directly read the status of each joy

The program Digital Scope for the C-128 on page 106 reads and displays the paddle #1 input (POT X of Control Port 1) in an oscilloscopelike manner. (This program runs only on the C-128. C-64 users must provide routines to read the paddle input and to display the graphics on the screen. We will provide some additional information on this later.)

Refer to the I/O Pinouts in the appendix of your User's Guide. That picture looks just like the side of the connector to which you will solder the wires.

nect the middle terminal of the pot (the "wiper") to the wire from pin 9 (POT X). The other terminal of the pot and the pin 5 wire can be left unconnected. If you have a sol derless breadboard, the best way to do this is to solder two wires to the pot terminals, and plug these wires into the breadboard. Then plug the wires from the connector into the breadboard. (For those unfamiliar with the breadboard, the five holes in each vertical line are internally connected so that up to five wires can be joined together simply by plugging them all into vertically adjacent holes.)

THE SOFTWARE The Digital Scope program turns the C-128 into the world's slowest digital oscilloscope. On the plus side, it is

corresponding to this averaged (filtered) value. It is displayed as a separate trace above the current input value on the screen.

This averaging routine is the most sophisticated part of the program. The plotted Y values are kept in a circular buffer YV() consisting of MAX elements. The pointer PTR cycles from 0 to MAX-1. At line 160 the pointer is updated to point to the oldest element in the buffer. The sum of all the values in the buffer is kept in SUM. In line 170, the oldest value in the buffer is subtracted from SUM and the current value of Y is added. Then the current value of Y is put into the buffer, replacing the oldest value. The run ning average is the sum of the values in the buffer SUM divided by the number of items in the buffer MAX. This is calculated in line 190, and in line 200 it is plotted 50 units above the actual input value.

The short routine at line 210 decides if the point to be plotted is on or off the screen. If it is on, it is plotted. If

it is outside the range of 0 to 200, an arrow appears either at the top or bottom of the screen showing where the image is. You may use the adjustment keys discussed below to bring the image back onto the screen.

The keyboard is checked after each horizontal position is plotted. If no keys are pressed, the next value of X is chosen in line 250. When X reaches 320 at the right side of the screen, the screen is cleared in line 260 and the next scan begins at the left side of the screen in line 120.

The program uses the 320 by 200 high-resolution display

Line 70 sets die high-resolution graphics mode and clears

the screen. Line 80 sets the initial gain G which converts

the 0 to 255 range of the A/D into a 0 to 190 range to fit onto the graphics screen. Increasing G is equivalent to mag nifying the vertical size of the image. VY in line 90 is the vertical offset of the image. Increasing VY moves the image higher up on the screen. Line 100 prints the Y value to be plotted on the screen. If this number is outside the range of 0 to 200, the image is off the screen. This value is printed on the default text screen, not on the graphics screen. It is for reference only. The main loop starts at line 110. The horizontal X value is defined by the FOR/NEXT loop. The vertical Y value is calculated in line 130. The computer reads the value of POT AX plugged into Control Port 1 (paddle #1). The input value is multiplied by G and added to VY to determine the corresponding screen value.

until you have all the SYNTAX ERRORs out of your typedin program. Commodore 64 users have more of a task ahead of them,

although it should be enjoyable and worthwhile. You must provide a high-resolution bit-map routine to plot a point

at position X,Y. A routine to do this was presented in the April 1986 edition of the Rupert Report. You must modify

the keyboard routine of the program if dynamic input is desired. Also, C-64 users must provide a routine to read the pad dle values. A complete routine is listed on page 347 of the

C-64 Programmer's Reference Guide. Paddle tt\ and Paddle #2 (Control Port 1) can be read with the commands: PI = PEEK(54297) : P2 - PEEK(54298). The C-64 manual says that paddles cannot be read reliably from BASIC, al though it seems that the main problem is with the reading of paddles in Control Port 2. Run this program (on the C-64 or the C-128) to display the paddle values from Control Port 1:

1 PRINT PEEK(54297),PEEK(54298) 2 GOTO 1

THE POSSIBILITIES

There are countless ways of using this program. Experi ment with changing the running average buffer length to see how more or less filtering of the input affects the out put. If you put a switch in line with one side of the poten tiometer, you can generate square waves by periodically opening and closing it (or simply connect and disconnect the wire to the pot).

Look at the filtered waveform to see how this low-pass filter converts a square wave into a triangle wave. You will see that if the switch is operated quickly enough, the filtered output can't keep up with the input changes, and it reaches a constant level. This is low-pass filter theory right before your very eyes! A nice thing about this simulation is that

it all happens at a speed which is easily comprehended by human minds. The snail's pace of BASIC is a benefit here. You could rig up a simple spring and lever mechanism to the shaft of the potentiometer in order to measure force or displacement. It would not require much effort to turn this program into a data-logger which stores the incoming data for future reference and interpretation. Your computer with its A/D converter is a laboratory in itself.

MAKING MUSIC

This gives generally consistent results on the C-128 in C-64 mode, with just a few glitches.

LEROY'S CHEATSHEET

One of the more entertaining uses of this program that I have found is to replace the potentiometer with a Cadmi um Sulfide photocell described earlier. The photocell acts like an optically controlled potentiometer. Increasing the amount of light on the photocell decreases its resistance and vice versa. Add this line to the program:

205 SOUND 1,20000 - 1*100,2

Now you can change the pitch of the sound with your hand simply by covering and uncovering the photocell. The

WEBSTER WORD GAME

ROW = INT(Y/8) Next, the dot's horizontal position, or X coordinate, must also be divided by 8. The result of this operation will be the column number of the eight-byte rectangle in which the dot appears. The formula used can be written:

COL = INT(X/8) When the two operations above have been carried out, the dot's horizontal position within its eight-byte rectangle must be calculated. This formula will do that job:

GUARANTEED SOFT"1

LINE = Y AND 7 When all that's done, a formula like this can be used to bring all the previous formulas together and calculate the position of the byte in which the desired dot appears:

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

HOW IT WORKS As in the previous formulas, the variable ROW in the above formula represents the horizontal row in which the rectangle that contains the dot appears, and the variable COL represents the vertical column in which the rectangle is sit uated. BASE represents the starting address of the screen map being used, and LINE represents the line number of the desired byte on a 200-line high-resolution screen (with the lines numbered 0 through 199). The ROW variable is multiplied by 320 because there are 320 dots in a screen line, and the COL variable is multiplied by 8 because there are eight lines of bytes in each screen rectangle.

ONE LAST DETAIL After this last calculation has been carried out, one com

plicating factor still must be taken care of. The complication is that the eight bits of data which form each byte on the screen are also arranged in a different order in RAM from the order in which they appear on the screen. In memory, the bits that make up a byte are arranged from right to left. But on the screen, the eight dots that make up a byte are arranged in just the opposite order: from left to right. Because of this complication, one last formula must be used to reverse the positions of the bits in a byte so that they will appear in the proper order when they are displayed on the screen. This formula is often written this way:

ON WITH THE PROGRAM Now that we know how a dot's position on a screen can be converted into its corresponding position in RAM, we're ready to see exactly how this month's RECTANGLE.S pro gram differs from the HRDEMO.S program described in this space last month. The most important difference is this: Every time HRDEMO.S plotted a dot, it used the series of formulas presented above to calculate the dot's position on the screen. But RECTANGLE.S does not perform every

shift right) instructions. Since the bits in a binary byte pro gress from right to left in powers of two, the easiest way to divide a bit by 2 is to shift each bit in the byte one place to the right. Shifting each bit two places to the right is equiv alent to dividing the bit by 4, a three-bit shift to the right is the same as dividing by 8, and so on. So three shifts to the right are used to divide the contents of the accumulator by 8 in the RECTANGLE.S program. In lines 112 through 126, the row number that has just

lines 97 through 141. As the table is created, it is stored in a block of memory that begins at memory address $8000. Actually, two tables are set up in this section of the pro gram; the low byte of each Y address is stored in a table that starts at memory address $8000, and the high byte of each Y address is stored in a second table that begins at $8100. This may sound like a strange way to set up an ad dress table, but it makes good sense, since die same offset that is used to fetch the high byte of a Y address can also be used to fetch the low byte.

been calculated is multiplied by 320 using a multiplication

subroutine that appears in lines 77 through 95. This routine looks much like the 16-bit multiplication subroutine that appeared in the HRDEMO.S program last month, but a close comparison will show that it's a few bytes shorter. And every little bit (or byte) helps when you're trying to speed up a program. After each row number has been multiplied by 320, the

After the program has created its Y-lookup table, it moves on to the process of drawing a rectangle on the screen —

with the help, of course, of values POKEd in during the execution of the RECTANGLE.BAS program. When the

necessary values have been POKEd in, the program first calculates the X offset that must be used to display each dot. It performs this calculation in much the same way that

last month's program did. But then, in lines 293 through 300, it looks up the starting address of each screen line.

Finally, it adds each Y line address to the appropriate X coordinate with the help of indirect (Y-register) addressing, and thus determines the location of the byte in which each desired dot appears.

ANOTHER SHORTCUT Still another tricky shortcut is used in lines 308 through 310 of RECTANGLE.S. In these lines, the equation

is solved by using another table —a very short one that ap pears in line 52. Since the purpose of this formula is to reverse the order of the bits in a byte before displaying the byte on a screen, the solving of the equation can be speeded up significantly by dispensing with calculations altogether and resorting to the use of a table. I'll leave it up to you

to figure out why. Now you know how to draw lines and rectangles on a highresolution screen at speeds matching those achieved in com mercial-grade graphics programs. Next month we'll reveal some more tricks of the trade and see how joysticks, pad dles, and mice can be used to control fast-action graphics on a high-resolution screen. □ SEE PROGRAM LISTINGS ON PAGE 104

Second, load and run the BASIC loader program to install the machine language program into a safe spot of memory. Last, load your copy of COMAL 0.14 and run it as usual. That's it! When you are ready to dump a screen, make sure the printer is turned on and the pa per is adjusted correctly. Then enter this command: SYS 52736 < RETURN >. The picture will be printed side ways in about 2Vi minutes. If you've ever used a BASIC screen dump (over an hour) or a COMAL version (about

25 minutes), you'll really like the speed improvement this program makes. The SYS command can be entered from within a running program or from the keyboard. It re sides in the RS-232 buffer area ($CE00-$CFFF), so it shouldn't be affected by any normal programs that you write.

REPROGRAMMING THE 128 HELP KEY If you think the HELP key on the Commodore 128 is for wimps, good news: you can reprogram it. The method is a little more complicated than the KEY com mand, but not much. Set AS, in line 10, to any BASIC 7.0 keyword or series of keywords. If immediate execu tion is desired include CHR$(13) in the manner shown. The HELP command is still available by typing it in di rect mode. -Ed Horgan Coatesville, PA

STRINGING MACHINE CODE ROUTINES At times it is convenient to stash short machine lan guage routines within a BASIC program to avoid con flicts, or to leave the customary memory areas free for other uses. The program segment shown here allows a machine code routine shorter than 256 bytes to be housed within a BASIC program in such a way as to be visually readable, LISTable, EDITable, SAVEable, LOADable, and executable with no problems. It requires no DATA statements, so it does not interfere with normal use of BASIC'S RESTORE command. The example code shown

is the "RESTORE LN" routine by Bob Renaud published in the March '86 Ahoy! Three-digit decimal machine code bytes separated by a single space are typed into strings Dl$, D2$, D3$, etc. Upon running the program, the code numbers are sequen

tially concatenated into string MC$ by Line 200 and the subroutine in Lines 140 and 150. At any time thereafter the DATA pointer can be restored to any desired line num ber by a program line like line 240. This equates MC$ to itself to ensure that its text is at the bottom of the ac tive strings area at the moment of use, so its address can be found by PEEKing locations 51 and 52. The routine is executed by a SYS call to that address, followed by a comma and the target line number. — C.C. Stalder Waynesville, NC

You are supposed to be able to put a plus or minus sign in front of an X or Y coordin ate in the BOX, CIRCLE, DRAW, LOCATE, PAINT,

SSHAPE, and GSHAPE commands to move the pixel cursor relative to its last location. But, if you use a mi

nus sign, an "ILLEGAL QUANTITY ERROR" is gen erated. However, there is an undocumented form of rel ative pixel cursor placement which will work with all of the above commands. (It is described in the System Guide, but only for option #3 of the MOVSPR com mand.) Whenever a coordinate is called for in the com mands named above, you may substitute a distance from the current pixel location along a specified angle by sep arating the numbers with a semicolon instead of a comma. For example,

GRAPHIC 1,1:DRAW 1,45,100 TO 100;90 TO 1 30;310 TO 104;180 TO 120;90 TO 50;235 TO 144;270 TO 50;305 TO 106;90 will draw a very crude rendition of a sailboat. Experi ment; I think you will find it to be a useful addition to your programming arsenal. -Rick Rothstein Trenton, NJ

EXPRESS YOURSELF WITH RESTORE According to the Commodore 128 System Guide, the RESTORE command can have a line number after it to determine which DATA statement is read next. What the Guide doesn't say is this line number need not be a simple

numerical constant, but rather can be any valid mathe matical expression! For example, consider RESTORE 100 + 10 * EX where EX is an expression composed of any correctly posed combination of string and numeric functions that equates to integer values. If EX=0, then the DATA

statement at line 1000 would be RESTOREd; if EX=1, then line 1010 would be RESTOREd; and so on. As it turns out, the RENUMBER command will work cor rectly with these mathematical expressions provided the first value in the expression is a constant which repre sents a valid line number. In the above example, RE NUMBER would change the constant 1000 to the same number that line 1000 becomes. However, RENUMBER will not look beyond the first constant it finds; so chang ing the line number increments will probably invalidate the RESTORE expression.

QUICK C HAiVGE For the C-64

And, to top it off, you're beginning to notice that your lines of data have the number 86 all over the place. You know it was supposed to be 96. Those darn gremlins. Now you'll have to spend another eternity finding and changing all of their mistakes. Well, it could be worse. At least you don't have a splitting headacheâ&#x20AC;&#x201D;yet. But, somehow, you know one is on the horizon. Wouldn't it be nice if you could just take two aspirins and call the computer in the moming? Better yet, how about telling ol' Reliable what to change and letting it do the work? Quick Change automatically changes anything you

Changes from 100 to 350 would be entered 100-350 and changes from 500 to the end of your program would be like so:

Now load the program you want to change. Quick Change can be switched on and off by typing SYS 50000 and pressing RETURN. The first SYS switch es it on, the second switches it off, etc. A message will let you know whether it's on or off. It's a good idea to leave Quick Change off while you load, save, or run a program.

Quick Change is in the NORMAL mode when you

first enter it. In this mode it only changes (or erases) entries that are not part of DATA or REM statements or contained in quotes. As an example, if you were chang ing PRINT to INPUT, it would be changed from this:

100 PRINT "PLEASE PRINT YOUR NAME"

When you're ready to start making changes, switch

Quick Change on. To use Quick Change, press any let ter key (A-Z), then RETURN. (This is faster and easier than having to type a SYS number every time you want to change something.) Quick Change asks for the old entry. You can enter up to 26 characters. They can be anything, including cur sor control keys, function keys, and keyboard graphics. After you've answered and pressed RETURN, you'll be asked for the new entry. It, too, can be anything, up to 26 characters long. If you're using Quick Change to erase the old entry, don't give a new entry. Just press the RE TURN key. "ERASE" will appear, verifying this choice. Next you'll be asked to enter the range of lines you want the change to occur in. This is done in the same

The REM mode works like the DATA mode. The dif ference is that only REM items can be changed. CON TROL and R brings you here. The ALL mode is just what its name implies. It chang es all occurrences of the chosen victim. CONTROL and A does the job. In the ALL mode a command to change PRINT to INPUT will change it everywhere. These lines:

CONTROL and D enters the DATA mode. Now only DATA items can be changed. So, if you wanted to change data number 123 to 169, 200 DATA 123 would now be

The various modes and their appropriate keys are listed on the screen. Whether you're changing or erasing, remember to be accurate about defining the item. Suppose you want to change the data numbers 129 to 169. If you answer the OLD ENTRY? prompt with 2, and the NEW ENTRY? prompt with 6, every 2 in the data range you specified will be changed to a 6, whether it's 2, 22, or 92. This can easily be avoided by answering the OLD ENTRY? prompt with 129, and the NEW ENTRY? prompt with 169. As another example, if you answer the OLD EN TRY? prompt with REM and the NEW ENTRY? prompt with DATA, the following will result:

When changing a line, Quick Change doesn't allow ex cessive length. For example, if you decide to change REM to PRINT and, as a result, one of the lines will exceed 80 characters, Quick Change stops and displays the ex cessively long line. It also lists the line as it currently appears in the program so that you can make whatever corrections you might want. Quick Change can be brought to a halt at any time by pressing the STOP key. To reuse Quick Change, press any letter key (A-Z), then RETURN. Experiment with Quick Change. It's simple to use and

DVORAK KEYBOARD For the C-64 and C-128

By Jim Partin If

you'd like to switch your

C-64's or C-128's keyboard from the standard QWERTY to the more efficient Dvorak layout, endure the old method long

enough to enter Dvorak Keyboard. The programs use a software method to activate the Dvorak keyboard; no hardware change is necessary.

Versions are included for the C-128 (in 128 mode) and the C-64 (or 128

in 64 mode). The programs don't use machine language wedges to imple ment the Dvorak layout, but modify the Kernal keyboard decode tables. Because of this, the new layout will work with a large number of pro grams provided the programs don't A) use the RAM that holds the new Dvorak layout or B) alter the memo

mode on the 128 and wish to return to QWERTY mode, just hold down

the RUN STOP key and hit the side reset button. When you are dumped into the monitor, hit 'X' and RE TURN. If you do accidentally hit RUN STOP/RESTORE on the 64 and want to return to Dvorak mode without rerunning the program, you can simply type POKE1.53 and press < RETURN >.

With some imagination, you can figure out a way to make Dvorak key caps for your C-64 keys. Brown masking tape is best, since it will lift off without a fight if you elect to re vert to QWERT. The Dvorak layout is becoming more popular all the time. I hope these pro grams will help you get a taste of the future of computer keyboards. □ SEE PROGRAM LISTINGS ON PAGE 127

ry locations that allow the alternate keyboard layouts to exist. While most

public domain or magazine published programs will work, many commer cial programs will not work. Cart ridges such as the Epyx Fast Load may also have to be disabled to work with the new layout. Refer to the il lustration for the new Dvorak key board layout implemented by the pro grams. Also, be sure to save the ver sion of the program you type, as both

In the midst of the shifting darkness over the Castle Sarnoth, slithering shapes moved up the royal road, over the moat and into the castle. Guards rushed into the court yard to battle with the shadowy figures, seeking to protect the king, and their screams were the only indicator that they survived for even a moment. As the sun was eclipsed, there appeared four sets of glowing eyes in the darkness before the king. The counselors fell to their knees with horror, and the court jester began cackling madly.

of it using system jumps to machine language routines. Well, here it is. I think you will agree that it is super ior to most commercial games of this type, both in speed and quality. My one regret is that I could not throw in more monsters, but the program is a typing chore as it stands. I think you can type it in over two or three sit

THE COMMODORE MAGAZINE THAT OFFERS YOU MORE

REVIEWS 1541 is equipped with a pair of 6522 Versatile Interface Adapter large scale integrated circuits (VIA chips). The VIA is a specialized chip designed to handle serial and parallel commun ications among the various compo nents of a microcomputer. Each VIA has two complete bidirectional eightbit data ports. Of these four eight-bit ports, the 1541 only utilizes three. In fact, the fourth port is not even con nected to anything inside the disk drive. If you haven't guessed it by now, the 40 pin DIP sockets on 21 Second Backup's cables hook up to the un used port inside the 1541. To accom plish this you will have to open up your disk drive and pry out the ap propriate VIA chip from its socket (remember there are two VIAs in ev

ery drive). The 40 pin DIP socket is then pushed into the one on the 1541's circuit board and the VIA chip is re installed into the 40 pin DIP socket. The installation actually extends the 1541's VIA socket while permitting access to the unused parallel port.

The computer end of the cable goes directly to the C-64's user port.

This port is internally connected to

a 6526 Complex Interface Adapter (CIA chip) which is actually a big brother to the 6522 VIAs in the disk drive. If you have been following along until this point you will not be surprised to learn that the C-64's us er port sports an eight-bit bidirection al data port originating from the builtin CIA. The result is a fully wired eightbit parallel bidirectional channel be tween the C-64 and one or two 1541 disk drives. In fact, since the VIA and CIA are tied directly to the mi croprocessor's data bus, this channel is as fast as the 6502 in the 1541 and the 6510 in the C-64 can be program med to read and write data. This is very fast indeed.

21 Second Backup provides three high speed full disk copy utilities on its accompanying disk. The first util ity is the basic copier which will du plicate unprotected disks as well as most basic copy protection schemes.

ingly enough, the 21 Second Backup program disk is copy protected and it will not copy itself! Not unexpec tedly, there are several forms of copy

protection on the market which are resistant to any and all 1541 copy schemes due to the built-in limitations of the disk drive's hardware. As with other nibble copiers, 21 Second Backup relies on parameter files to handle these uncopyable schemes. The parameter list provid

ed with Version 4.1 of 21 Second Backup contained only a single entry for Accolade Software. Interestingly enough, it did not work on the copy of Fight Night upon which we tried it. VG Data Shack justifies the limi tations on what 21 Second Backup will copy by saying that "(allowing the program to copy everything) would quickly accelerate the advance of copy protection."

Note that hot and mug gy summer days, without air condi tioning, will reduce static buildup. In any case, avoid direct contact with the VIA's pins.

The connection to the disk drives never gets in the way of any 1541 op erations, since the disk drive VIA port used by 21 Second Backup does not really exist as far as the 1541 DOS is concerned. The connection to the computer's user port will have to be

The Apple 11+ Emulator for the

■ Runs Apple 11+ software such as:

Commodore 64

DOS 3.3 APPLESOFT

INTEGER BASIC

APPLE PASCAL

CP/M (with a Z80 add-on)

■ Provides eight standard Apple compatible peripheral slots that ena ble you to add:

" SI) COLUMN CARDS

Z80 CARDS MEMORY EXPANSION BOARDS 64K BUFFERED PRINTER CARDS DISKDRIVE CONTROL LER CARDS MOUSE CARDS ■ Provides four software select able C64 cartridge slots accessible by a built-in software command. This eliminates the need to power-up and power-down which is necessary on the C64. ■ TheSPARTAN DOS CARD enables your 1541 disk drive to read both Commodore and Apple pro grams. This eliminates the need to purchase an Apple disk drive. ■ Permits simultaneous process ing. Because the SPARTAN has its own CPU and 64K memory, you can print a program on the SPARTAN at the same time you are running a separate program on a C64.

■ Provides two video outlets: selectable SPARTAN/C64 and

dedicated C64. This feature makes it possible to view both an Apple and

a C64 program at the same time. ■ Opens the door to new cus tom programming capabilities. A programmable keyboard function allows simultaneous communication with both the SPARTAN and C64 CPUs. ■ The SPARTAN system ena bles access to machine level code in both the C64 and SPARTAN machines. This feature is unique to the SPARTAN and opens a new level of possibilities to the avid programmer.

■ The SPARTAN comes with two custom Phantom ROMs. These ROMs contain commands that ena ble you to customize your working environment with programming modifications. For example: Turn either the SPARTAN or the C64 into a slave of the other machine. Use either the SPARTAN or the C64 as a RAM disk or printer buffer for the other machine. Run two monitors simulta neously, one in SPARTAN, the other in Commodore.

■ Run Apple programs with a joystick, or any other communica tions peripheral. At the same time you can still run a Commodore pro gram on the C64. This allows two people to use the SPARTAN/C64 combination as two separate computers.

■

The SPARTAN has an open

architecture design with accessible ROM sockets which allows you to install your own custom ROMs. ■ The SPARTAN is designed to interface with all ports and connec

tors on the G>4. These same

ports and connectors are duplicated on the back of the SPARTAN, thereby preserving all C64 hardware capabilities. The SPARTAN opens the Apple environment to Commodore users by allowing access to Apple 11 +

add-in boards, software and peripherals. __l

MKXH3AMMING CI-IAIJJENGIES By Dale Rupert

ach month, we'll present several challenges de

signed to stimulate your synapses and toggle the bits in your cerebral random access memory. We invite you to send your solutions to: Commodores, c/o Ahoy! P.O. Box 723 Bethel, CT 06801 We will print and discuss the cleverest, simplest, short est, most interesting and/or most unusual solutions. Be

sure to identify the name and number of the problems you are solving. Also show sample runs if possible, where appropriate. Be sure to tell what makes your solutions

unique or interesting, if they are. Programs on diskette (1541 format only) are welcome, but they must be accompanied by listings. You must en

PROBLEM #34-3: DIGIT DECOMPOSITION The user enters any positive integer up to nine digits long. Write a program to print out the individual digits and their sum. If the user enters 1234, the computer dis plays "1 + 2 + 3 + 4 = 10." One slight catch: no strings (except the "+" and "=") and no string functions are al lowed. Still an easy problem, isn't it?

close a stamped, self-addressed envelope if you want any

of your materials returned. Solutions received by the mid dle of the month shown on the magazine cover are most likely to be discussed, but you may send solutions and

comments any time. Your original programming prob lems, suggestions, and ideas are equally welcome. The best ones will become Commodares\

PROBLEM #34-1: DISTANCE FINDER This problem was inspired by a suggestion from Yuk Hung Mak (Curacao, Netherland Antilles). The user spe cifies the width (W) and height (H) of a grid (such as 320 and 200 for the C-64 graphics screen). Assume the points in the grid are numbered sequentially from 1 to (W times H). The user specifies two points A and B which are each between 1 and (W times H). The com puter calculates the straight-line distance between those two points.

An example will clarify the problem. If W=320 and H=200, point number 1 is in the upper left corner of the grid. The upper right corner is point number 320, since the grid is 320 units wide. Point number 321 is at the left edge of the second row, and number 640 is at the right edge of that row. The bottom left and right corners are numbered 63681 and 64000 respectively. The distance from point 1 to point 63681 is 200 (top left cor ner to bottom left corner). The distance from point 1 to point 320 is 320 (top left corner to top right comer). The distance from point 1 to point 64000 is 377.36 with help from our friend Pythagoras.

PROBLEM #34-4: MIX COUPLES Here's a good one from around the world, submitted by Necah Buyukdura (Ankara, Turkey). Using the first letters of the first names of twelve people (six couples), we are told: C, F, P, Q, and T are YOUNGER; A, D, E, F, and Q are TALLER; D, P, Q, S, and T are DARKER;

and A, C, P, S, and U are SLIMMER than their spouses.

(B and R are not mentioned above.) Write a program that will deduce and then print six pairs of letters, each pair giving the first name initials of each couple.

We received several good explanations for the "PRINT CHR$(34)" puzzle/bug mentioned at the end of the June Commodores. The problem was to explain why

PRINT MID$(CHR$(34),1);2;3 prints reverse-video right brackets after the two and the three. The explanation is that printing CHR$(34) puts the computer into the "Quote/insert" mode. In this mode, cursor movements show up as special symbols. In partic ular the cursor-right mode is a reverse-video right brac ket. When the computer prints the number "2," it prints a space where the optional minus sign might be in front of the digit, and it also prints a cursor-right character

Art sent the following program to provide further in sight into how the Quote mode works. •1 REM QUOTE MODE DEMO BY ART SHIPMAN

TO 5

•6 PRINT Q$;:POKE PK,1:PRINT PEEK(PK);:GO TO 6

Line 1 sets PK to the address of the Quote mode flag. For the C-128 the address is 244. If DS$ has a length of zero, then the program is being run on the C-64, and PK is changed to the appropriate value of 212. Q$ is a quotation mark. Line 4 is executed repeatedly until you press the RUN STOP key. You will see the quotation mark followed by the current value of the Quote mode flag (1) and the right bracket discussed above. The next time line 4 is executed, another quotation mark is printed followed by the number zero (without the right bracket), indicat ing that the computer is no longer in the Quote mode. Press RUN STOP and type GOTO 5. This line repeat edly takes the computer out of Quote mode by POKEing 0 into address PK. No more right brackets are dis played. Press RUN STOP again and type GOTO 6. Now the computer is consistently put into Quote mode, and the " 1]" is continuously displayed. Art even suggested a reason for the use of the right bracket. In the 1541 Us er's Manual under the PRINT# section, it mentions that

requires six minutes to list. If you are interested in Jim's machine language routine and BASIC program, send me a self-addressed, stamped envelope, with your request clearly stated, to Commodares.

Now on to the Commodares from the June issue. All of the solutions to Problem §30-1: Functional Entry used the dynamic keyboard technique. The problem suggested by Glen Bohusch (Erie, PA) was to allow the user to run a program, type an expression for a user-defined func

tion, and have the program evaluate that function for vari ous values. The solution from S. Simonetti (Glen Rose, TX) is listed below.

This program runs on the C-64 and the C-128. The keyboard buffer and queue counter are in different loca tions in the two machines. Line 8 assumes a C-128 is being used. If the program is run on a C-64, line 9 chang

If you are writing software that may be run on various machines, you should consider using some of the ideas of this program.

memory locations. Consequently it is very easy to adapt Jim's program for screens of any width. To use this on the C-128 with an 80-column screen, just make these changes:

The problem was to write a program which could deter mine the type of computer as well as the operating modes and screen colors of the computer on which it is being run. Since the program contains some of the new C-128

Line 10: change 39 to 79 (one less than screen width)

Line 100: change 40 to 80 (equal to screen width) Line 140: change 41 to 81 (one more than screen width) Jim uses the < BACK ARROW > as the escape key for

this program. Press it when you are done typing.

Other very good solutions to this problem were from Paul Sobolik (Pittsburgh, PA), Steven Steckler. and Ben

Margolin (Detroit, MI). Congratulations to Ben and the rest of the computer team at Renaissance High School who are three-time city champs, and who made it to the

international championships in Detroit this year. It was easy to separate the correct solutions from the incorrect ones to Problem #30-4: Color Bars. The read ers who felt that it was very likely for the screen to even tually be filled with one color generally misinterpreted the problem. The length of each character bar to be printed was determined by the greatest number of con secutive repetitions of any one color previously chosen, where colors were randomly chosen from 16 possibilities. Until two consecutive matching colors are randomly cho sen, color bars are printed singly. After the first occur rence of two consecutive matching colors, color bars are each printed two characters in width. This continues un til three consecutive matching colors are chosen, after which color bars are printed which are each three char

a solid color, since 32*32 is greater than the 1000 char acters needed to fill the screen. That means that the same

random number must occur 32 times in a row, and that's not very likely at all. Based upon some preliminary tim ing and the results of a simulation program he wrote, Jim concluded that it would take on the order of 1028 years (that's one with 28 zeros after it) on the average for the screen to be one color. Jim points out that this assumes the random number generator is truly random. In actuality it generates a very large but finite group of numbers. If in that group there is no occurrence of 32 consecutive numbers which are the same, the solid col or screen will never happen.

Alain Goyette (Gander, Newfoundland) wrote an as sembly language program to solve this problem. He and Scott Nicodemus used the random noise generator of the

SID chip to generate random numbers as described in Tips Ahoy! in the June issue. In BASIC, POKE 54287,255 EEK(54299)

bers from 0 to 15. Alain ran his BASIC program for three days and never got a color bar of length greater than five. His assembly language program did better with a length

CHECKUPTI

tory block count was the number of blocks in the file when it was saved, so if the block counts disagree, ei ther the file is a different file than shown in the direc tory, or part of the file has been lost.

Disk Checkup will detect any case of file overlap, in cluding partial overlap, because it checks each block for overlap during the trace. If a problem is found, the over lapping files are identified. Unlike Validate, Disk Check up will not abort if it encounters an illegal file link, i.e. a link to a nonexistent track or sector. If it encounters an illegal link during a trace, it prints an illegal link mes sage, and continues with the next file.

It is not necessary to monitor Disk Checkup while it works, since tracing all the files on a full disk can take

a few minutes. On the final screen Disk Checkup displays a full status report on the disk files and three Blocks Free. To bring a problem disk back to health, a general guide line is to first Validate (Collect) the disk, delete any prob lem files, and Validate again. Disk Checkup is safe to run on all disks because it does not write to the disk. If a disk contains REL files, they may be incorrectly identified as problem files, because REL files use a different directory format from PRG, SEQ, or USR files. Disk Checkup is written in 2.0 BASIC in a structured format, yet with an eye to speed. The pro gram includes many REM statements that may be omitted if desired. D SEE PROGRAM LISTING ON PAGE 128

Disk Checkup displays all three. In a healthy disk all three should agree. An exception is some commercial disks that may use a nonstandard BAM or directory. Disk Checkup, however, does much more than display three Blocks Free. It thoroughly checks each file in the directory. In testing this program on three of my heavily used working disks, which contained about 150 files, I found three previously undetected problem files. Disk Checkup first displays an expanded directory, including the starting track and sector of each file, and then checks that all files start at different track and sectors. This is a quick check that will detect the most common DOS file error: two directory entries pointing to the same file. Disk Checkup then proceeds to trace each file. If the traced block count does not agree with the directory block count, the file is displayed in inverse video. The direc

My friends and I write BASIC programs, and we have heard of tricks and techniques that will allow our pro grams to run faster. Using these techniques, is it possi ble to write arcade-speed games without machine lan guage? Also, could you tell us what kind of techniques we could use to speed up our BASIC programs? Due to the way the BASIC language is translated by the C-64 and C-128, commercial quality animated ac tion games are very difficult to implement successfully. BASIC is interpreted statement by statement, each state ment taking possibly dozens of machine language steps to execute, not including the time or effort the BASIC in terpreter spends just parsing (decoding) your program line into separate byte-sized pieces. The most efficient method of programming such a game would be to use machine language (actually assembly language would be the correct term, but the two are more or less interchange able) which is not as difficult as you may think. So to answer your first question, arcade speed games are ex tremely difficult if not impossible without at least some

AD = 3.14 * 15 2) Put all commonly used subroutines in the begin ning of your program. This is probably the opposite of what you were taught, and will require extensive rewrit ing of your program, but if you are trying to write fast code this is a must. 3) Replace the number 0 (zero) with a period (.). 4) Integers are supposed to run faster than floating point numbers, but timing program execution proves this to be false. So use floating point, even though the latter may use more memory.

5) While using FOR/NEXT loops, don't name the vari able of the loop after the NEXTâ&#x20AC;&#x201D;it was intended to be optional on most home micros. An example should clear up any problems: FOR X = 1 TO 1500

Seeing so many programs in all the Commodore mag azines, I wondered what the formula for converting the SYS, PEEK, and POKE addresses from the C-64 to the C-128 would be.

ESCAPE FROM SKULL CASTLE (July '86} Five @ symbols were missing from the end of line 618 as printed. The error will cause an incorrect Bug Re pellent code to be printed for that line, but will cause no other problems. To generate the correct Bug Repel lent code, enter the line as follows:

618 PRINTTAB(21)"[RVSON][BLACK]NOP[RVSOF F] [RVSON]QR[BLUE][3"@"][BLACK]@[BLUE][6

Also, several readers reported incorrect Bug Repellent codes for all the data statement lines (1000-1178). This will occur if a user types in any line within the program with an incorrect number of quotation marks.

AHOY!

Unfortunately, the simple answer is that n# such for mula exists. Although from a logical standpoint, it might seem that one would just multiply every address by two and let the program go at that, this just won't work. The C-64 has ROM from $A0O0 to $BFFF and from $EO00 up. Saved within the ROM is the operating system, the program that controls everyfunction ofthe C-64from checking the keyboardfor recent input to interpreting your BASIC programs. The ROM is a machine language pro gram and even has variables that can be easily changed by a programmer. Since the C-64 and the C-128 don't

have identical operating systems, and because of the myr iad of differences between the two machines, a formula is impossible. What you can do is consult a memory map, a book that describes the function of most of the addresses in a specific machine, for both machines and lookfor similar labels (a label is a six letter name given to an address or routine) or junctions for the given address.

AHOY!

FLANKSPEED FOR THE C-64 By GORDON F. WHEAT Flankspeed will allow you to enter machine language Ahoy! programs without any mistakes. Once you have typed the program

in, save it for future use. While entering an ML program with Flankspeed there is no need to enter spaces or hit the carriage return. This is all done automatically. If you make an error in a line a bell will ring and you will be asked to enter it again. To LOAD in a program Saved with Flankspeed use LOAD "name", 1,1 for tape, or LOAD "name"8,l for disk. The function keys may be used after the starting and ending addresses have been entered. fl — SAVEs what you have entered so far.

D —LOADs in a program worked on previously. f5—To continue on a line you stopped on after LOADing in the previous saved work.

f7—Scans through the program to locate a particular line, or to find out where you stopped the last time you entered the program. tl temporarily freezes the output as well. 5
