The AsmComp( command converts asm programs to non ascii cutting the program size in half. It does not assemble asm progs! The Asm( command executes both ascii and non-ascii asm programs. The AsmPrgm statement tells the TI-86 that the program is in asm. To make 86 asm progs, assemble the source code the same way as in 83asm. Bill N. Author of the first TI-86 Asm game, Turbo Breakout 2
