I'm curious as to where the term P-code came from
and what defined it.
There's no formal definition of "p-code". Although other similar
"bytecodes" existed before, the term "p-code" or "pcode"
came from the
earliest implementations of Pascal, ncluding Pascal/S (subset) and
Pascal-P, starting around 1972. Those originally ran on the CDC 6600,
though the Pascal-P series of compilers were ported to many other machines,
and served as the inspiration for UCSD Pascal.
