Have you ever heard of preprocessors?


I found the UNIX "as" assembler plus the "m4" preprocessor much more useful
than DEC's fully-featured Macro-11. For EXACTLY the same program on the same
processor: John-James FIG-Forth for the PDP-11. Some of the features of PDP-11
"as" are very nice indeed. Much more useful than combining two programs in one
piece (macro pre-processor and assembler).


Don't you prefer:


head(type,,docol,) / not entirely sure of the number
over; plus; swap / of commas in the macro here.
1: pdo; i; emit; ploop; 1b-.
semis


to:


TYPE:: HEAD <TYP,E>,,DOCOL ; Ditto.
.WORD OVER, PLUS, SWAP
XTYPAA: .WORD PDO, I, EMIT, PLOOP, XTYPAA-$
.WORD SEMIS
