Microsoft Macro Assembler Reference

The Microsoft Macro Assembler (MASM) provides you with several advantages over inline assembly. MASM contains a macro language with looping, arithmetic, text string processing, and so on, and MASM supports the instruction sets of the 386, 486, and Pentium processors, providing you with greater direct control over the hardware. You also can avoid extra time and memory overhead when using MASM.
