The syntax, directives, macro language, and lexical substitution operators of VAX MACRO formerly appeared in MACRO-11, the assembler for the PDP-11 series of computers. The MACRO-32 assembler supported the VAX processors developed and manufactured by DEC. It ran under the VMS operating system and produced object files suitable for the VMS linker. The MACRO-32 assembler and linker were bundled with the operating system.
To port VMS to the DEC Alpha, VAX MACRO was implemented for the Alpha architecture. Since the Alpha used a different instruction set than the VAX, MACRO-32 was implemented as a compiler, compiling VAX assembly language into Alpha instructions.[1]
The Alpha AXP chips have their own native instruction set architecture, the OpenVMS assembler for Alpha assembly code is named MACRO-64.[2]
A compiler from MACRO-32 is available for Intel Itanium architecture,[3] and for x86-64.[4]
