I have worked with mainframes systems for close to 15 years including IBM,
DEcsystem-10s and Unisys 1100. I can assue you that system software for these
systems include extensive use of MACROs. This is the only way to do the
software and much of the source is in the form of macros for the assembler or
is in a high level language. (PL/S [as I remember]. on 360 architectures,
BLISS-36 on the DEC-10 or PLUS on the 1100).
