Co. started the project in FORTRAN, but gave up, particularly
when it was realized that implementing data structures and recursion
in FORTRAN was going to be a bit of a task.
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.
