treats them.  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.
