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 6.11 is the last version of MASM that will run under MS-DOS
MASM 6.14 includes support for the Intel Pentium Pro processor, the Intel MMX architecture, AMD 3D Technology, and Intel Internet Streaming SIMD Extensions.
Due to changes in the MS-DOS extender used in earlier versions of MASM, MASM 6.14 does not run on Windows 3.1x or MS-DOS. Either Windows NT or Windows 95 is required to run MASM 6.14.
