RBASIC by King Computer Services. RBASIC for the Model 100/102 is a cross-compiler that runs on a PC or clone that will 'compile' Model 100/102 BASIC programs so that they can run directly from an Option ROM chip. RBASIC is not a true compiler, as the primary intention is to produce ROMable programs. The resulting program is partially compiled and partially left for the BASIC interpreter. It runs very slightly faster than the original but the speed increase is not significant. The output file is anywhere from 10% to 30% larger than the original depending on options that are chosen. The package supports all of the BASIC syntax except those commands that are unique to interpreted BASIC such as EDIT, LIST, STOP, CONT, MERGE, SAVE etc. It also supports ON ERROR, ON KEY, ON COM, ON TIME$ logic. The compiler output is in two phases. The first step produces an assembly language source code file that allows a user to see exactly what the compiler is doing, and also allows the file to be modified. The assembly source is then assembled into a .HEX file that can be loaded to a ROM burner or a Model 100/102. A special use of the MERGE verb allows embedding Assembly language source code directly in the BASIC program. The package includes all the utilities needed to upload and download to the PC, as well as compile and assemble. Price $199.95 King Computer Services, Inc. 1016 N.
