It expands them into individual assembler statements (i.e.,
instructions, labels, data definitions, etc.). VAX MACRO then translates
those into compiler intermediate language (originally GEM EIL [expanded
intermediate language], nowadays probably LLVM IL).
Neither the VAX assembler nor the VAX MACRO compiler treats macros as
high-level entities. I know of no assembler that would do such a thing.

Well,
doesn't it depend on whether VAX MACRO kept the macros as
high-level entities when translating them, or if it processed macros in
the familiar way into instructions that sat at the same level as
hand-written ‘assembler’. I don't think this thread has made that clear
so far.
The VAX MACRO compiler treats macros the same way that the assembler
