The Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows. For a time, it competed with Borland Turbo Assembler. IBM re-branded early versions under the name IBM Macro Assembler. Later versions were bundled with Microsoft Visual Studio.
Version 5.0 adds 386 instructions, but still only generates real mode executables.
5.1 and 6.0 include both MS-DOS and OS/2 versions of the application.
