MASM (Microsoft Macro Assembler) is an assembler for the computers:

x86 (32 bits) and
x64 (64 bits) processor architectures.

It translates assembly code into machine language and is primarily used for writing operating system (like MS-DOS and Microsoft Windows) components, dynamic link libraries (DLLs), and hardware-level programming within Windows environments.
