It also depended upon how the virtual machine was implemented. The
Apple Pascal virtual machine was horrible. Compiled Pascal programs
ran slower than their equivalent in interpreted Applesoft BASIC.

An another note, I have a UCSD-P Fortran for Macintosh, but I can't
use it because I don't have the UCSD-P system for Mac. Anyone have
this sitting on a dusty shelf somewhere?
