Integer Basic compilersWhy would anyone want an Integer BASIC compiler? Is IntegerBASIC still used? There are some cases where integer arithmetic isall that is required; for example in the typical game. If it requiresHIRES graphics, the result of any calculation will be scaled to be between0 and 279 or 0 and 191. It would certainly be possible to prescalethe numbers by, say, 1000 before performing any calculations.There would be plenty of precision left for the graphics coordinates.Even if the transcendental functions , sin, cos, tan, etc., are neededperhaps approximations would do (in the case of graphics). Even thesimplest approximation, x = sin (x), is within five percent at .5 radians(30 degrees). All of this may seem like a lot of work just to useFLASH!By Mike LaumerLaumer Research1832 School Rd.Carrollton, TX 7 5006214-245-3927$79.00$39.00 (Runtime Source}Machine Language48K, DOS 3.3UnlockedRating: A+INTRODUCTIONThe FLASH! compiler compiles Integer BASIC source code into6502 machine code for a considerable improvement in executionspeed. FLASH! can also create assembler source code compatiblewith the S-C Assembler II 4.0. There are also many enhancements toInteger BASIC.Reviewed by Edward Burlbawan "obsolete" language. So what is the tradeoff? First and foremost,Integer BASIC programs are typically twice as fast as those written inApplesoft BASIC. Integer doesn't directly support HIRES graphics;the machine language graphics routines must be used. Machine language,already compiled code, means speed, and that is probably themain reason to be interested in a compiler.The following two packages compile Integer BASIC into machinecode or near machine code. Each has its own set of extensions toadd some of the commands an Applesoft user might feel are~issingfrom Integer BASIC. Read on.THE COMPILERTo run the compiler simply BRUN FLASH and answer the questionsas they appear on the screen. FLASH! will compile memory tomemory, memory to disk, disk to memory, and disk to disk. A RAMcard can be used by the compiler for temporary storage during thecompilation process. The runtime code may be included or left out ofthe disk file. A self contained code is created which may be run on anApple without Integer BASIC. This is not true with the Applesoftcompilers. The programmer may compile with or without languageextensions and create a symbol table list, line number list, or assemblylanguage list (compatible with the S-C Macro Assembler II, or S-CAssembler II 4.0). The listing may be directed to a printer. Othercommands allow memory management, such as skipping over theHIRES pages.The ability to create assembler source code could be used as anIAsk Your Dealer AboutThe Sensible Product Line41Ql Sensible ~~Software6619 'PERHAM DRIVENCEMENTW.
