I've got disassembled versions of TP 3.01a and of both the commandline and IDE's
compilers of TP6. Happy to share them, with or without the permission of
Borland/Inprise/Embarcadero - I don't think MicroFocus belongs in the list...
By the way, a very long time ago someone on the FreeDos site mentioned that they
were talking to Borland about the same, but there was never any follow-up.
And for what it's worth, opening the source for Virtaul Pascal would be orders
of magnitude more useful, as it generates 32-bit code that still runs under
64-bit Windoze, and its IDE beats the shit out of the one that comes with
FreePascal, which, I'm talking about FreePascal itself, after 24 years still has
problems with some laughably simple programs that worked from TP2 to BP7.
