Microsoft. Macro Assembler Version 5.1 • For the MS® OS/2 or MS-DOS® Operating System Microsoft Macro Asset bier version 5.1 puts all the speed and power of assembly-lar uage programming within easy reach. Make your programs run faster by linking assembly-language subroutines to your Microsoft QuickBASIC, BASIC compiler, C, FORTRAN, and Pascal programs. Technical Highlights If you're accustomed to programming beyond the level of documentation the correct model for your subroutine, in a high-level language like Microsoft supplied with previous versions of just use the MODEL directive and choose QuickBASIC, BASIC compiler, QuickC, Microsoft Macro Assembler.
