This is a statement of personal opinion, Dave. You may think that they are all wonderful, but someone with different tastes (me, for instance) may not like these things at all. (Note: I only saw the non-concurrent Apple II version of USCD Pascal. Afterwards, I never wanted to see it again). Since I didn't play with the p-systems very long, I will ask what I consider the key question: How easy is it to change these things? More importantly, how easy is it to get rid of that (awfull, awfull, awfull) command processor the p-systems use? On CP/M, I can change all these things with ease (except for adding concurrency - that is HARD!). I don't EVER use the CP/M editor - I either use Mince or qed. I don't use the CP/M assembler; I work in C, LISP or Fortran. And the default command processor is ZCPR2 - but I could run the small shell (Unix-like commands & output redirection), microshell (Full I/O redirection & pipes), or the LISP shell I am working on (runs inside my LISP system). Is this possible on the p-systems?
