I think that if I wanted to build a Pascal compiler in FORTRAN I would
build a p-code engine in FORTRAN and implement the compiler in that.
But I don't know if they had the concepts to do that. Not that I think
that inventing a p-code engine was beyond them, but it certainly would
have raised the bar.
Wirth and Co. didn't invent P-code. I worked with a fellow who did a
P-code implementation of COBOL back in the 60s (it ran in a 6600 PP).
