by DAVID BARRY
The time is fast approaching that will test the mettle of the Atari-sponsored U.S. Women's Volleyball Team. And the testing will be tough; the U.S. is up against some formidable opponents. Eight teams have qualified for the Olympic sport of volleyball this summer in Los Angeles: The U.S., which receives an automatic slol as the host country; the U.S.S.R., the 1980 defending cham pion; China, the 1982 World Cham pion; and five other teams selected from the five continental championships in 1983: East Germany, Brazil,Japan,Peru, and Cuba. The teams will be broken into two pools, with three round-robin matches slated for each team. World ranking now places China in the number-one spot and the U.S., num ber two. But to capture the gold and dis place China from its throne, the U.S. must be mighty sharp. China is an awe some squad. In April, Atari sponsored a six-city tour of the United States in which the U.S. team played China.

Their team won five of the sixmatches, moving so quickly on defense chat it was difficultfor the U.S. to penetrateand score. Chinese sensation Lang Ping led their offensive force with her brilliant spiking power. At th� time, however, U.S. coach, Arie Selinger, pointed out

WILCOX Use it to program more efficiently SYNOPSIS George Boole, the founder of modern symbolic logic, developed Boolean algebra during the mid-19th century. Since then, extensive development of his original concepts, which use the symbolism of algebra in logic, has given Boolean algebra an extremely important role in computer science. 48 ANTIC, The Atari Resource oolean operations-those that yield true or false results-provideuseful programmingshortcuts. Use of Boolean operations can make your BASIC pro • grams run faster and occupy less space in memory. Boolean operationsalso can be used to monitor joystick posi tion, provide screen boundary limits, set flags, select values, • and replace successive IFffHEN statements. READING A JOYSTICK • • A joystick can be placed in any one of nine positions, each of which returns a unique value to the BASIC program. The following diagram represents these values. For example, a • • joystick pushed forward and to the left returns a value of 10, while a neutral joystick returns 15. A BASIC routine similar to the one below is a common • method of reading joystick motion. In the following Figure 1. examples, S is the value returned by the joystick: Joystick position values. 10 S: STICK(0):IF 5:15 THEN 10 20 IF S:7 THEN X:X+1 30 IF 5:11 THEN X:X-1 40 IF 5:13 THEN Y:Y+1 Compare INT(S/2) with S/2. The result of the expression: 50 IF 5:14 THEN Y:Y-1 (S/2 - INT(S/2)) is zero if S is even, and greater than zero if 60 IF 5:6 THEN X:X+1:Y:Y-1 S is odd. If you want to see how the two values compare, 70 IF S:5 THEN X:X+1:Y:Y+1 type in the following program line and RUN it. Type any 80 IF 5:10 THEN X:X-1:Y:Y-1 number and [RETURN] at the input prompt(?), and the pro 90 IF S:9 THEN X:X-1:Y:Y+1 gram will print out the two values. 0 INPUT 5:? INT(S/2),S/2: GOTO 0 Note that when the values of downward joystick move ments are divided by four, the remainder is always one. You can detect such downward motion with the following BASIC statement: INT(S/4)*4:S-1 This statement is only true when the joystick has made a downward motion. To see how these two values compare, type in the followingsample program line and RUN it. Type any number and [RETURN] at the input prompt (?), and the program will print out the two values. 0 INPUT S:?INT(S/4)'4, S-1: GOTO 0 We can summarize these modifications into a new BASIC routine: 10 S: STICK(0):IF 5:15 THEN 10 In this routine, X represents the horizontal position and 20 IF 5<8 THEN X:X+1 : REM JOYSTICK Y the vertical position of the character or player on your PUSHED RIGHT screen. If we take advantage of the joystick's numbering pat 30 IF 5>8 AND 5<13 THEN X:X-1 : REM JOYSTICK tern, we can use Boolean operations to modify the BASIC PUSHED LEFT code. 40 IF INT(S/2):S/2 THEN Y:Y-1 : REM JOYSTICK All movements to the right involve joystick readings that PUSHED FORWARD are less than eight. All movements to the left involve values SO IF INT(S/4)*4:S-1 THEN Y:Y+1 : REM JOYSTICK that are greater than eight, but less than 13. Even numbers PULLED BACK denote upward motion, and any even number divided by two gives an integer (or whole number). We check for even BASIC assigns a value of one to an expression which is numbers by comparing the value of a number divided by logically true.

If so, type enter it as text into the word processor. 3500 bytes of RAM, in addition to the "Y ", and the change is made. In this The global-search-and-replace function program being altered. It nms on all case, the name will appear twice in the makes quick work of changing all oc Atari computers. table: once in its original form, and once curances of a variable. in its new form. This is possible because Unfortunately, my friend didn't use the variables don't use the same token, any of these word processors on his cassette-based system. and may not have the same value. (AtariWriter is designed to be used with cassette systems Every variable used in a BASIC program is assigned its own -ANTIC ED.) After some thought, I attacked the problem token. Tokens are one-byte representations of variables that directly. Using a co-resident program to change variable are used to save space in memory. The token is assigned when names in the variable name table, the modified program can the variable is first used. This token is also tied to the vari be RUN or SAVEd without LISTing, modifying the text and able's corresponding value in the variable value table. The ENTERing the listed program. The result, RENAMER , accom RENAMER program "puts a new label" on a token. The value panies this article. the token refersto, and the way a program handles the token The RENAMER program appends new variable names to remain the same. RENAMER can give every variable in a pro the variable name table, then copies the table into a string. gram the same name without affecting the operation of the The new name is switched with the old name, and the string program. However, such programs should not be LISTed to is copied back into the variable name table. The RENAMER a cassette or disk; they must be SAVEd. program must be LISTed on either cassette or disk. First, The REN AMER program uses I 3 different variable names LOAD your BASIC program and compare it with RENAMER (start with Z) which are added to the variable name table. forconflicting line numbers.

You must tell RENAMER whether you're Dialogue with RENAMER requires a simple yes or no changing the name of a numeric variable, an array or a string. response. A capital "Y " means "Yes."

Developed in the early U1970's by IBM, floppies were first used in laboratory and office environments. They were developed to be an inexpen sive alternative to tape or cartridge storage. To achieve these goals, a thin mylar floppy disk enclosed in a thin jacket was used . Now floppies are found just about any place you can find an Atari. Un fortunately, floppies are vulnerable to physical damage caused by spills, dust, fingerprints, smoke particles and rough handling. Once a disk is damaged, it becomes prdctically impossible to retrieve data from it. Children, in particular, have a difficult time remembering how to handle ihese disks properly. To solve this problem, Amdek intro duced its AMDC three-inch disk drive. Available as a single (AMDC I) or a double-drive (AMDC 11) system, the tected by a hard plastic case.
