Subject: RE: [HECnet] PDP-11 Pascal or Modula-2?
Sorry to hijack this thread, but this reminds me. I would love to find ALGOL-68C that was
implemented on the DECSYSTEM-20. Any chance anyone might have it? I believe it may have
been on a DECUS tape, but I have not found it on any of the tapes I have looked at.
Thanks
Rob
Are you sure that Modula-2 came from the PDP-11?
I don?t remember it
there.
The comments in the source for the VAX compiler say it was?
The VAX Pascal compiler was adapted from the ETH
Pascal compiler for
the CDC 6000 mainframes; the generated code from VAX Pascal V1 made this
blatantly
obvious.
Do you mean VAX or PDP-11? Either way, I'm not surprised - the DEC-10
Pascal was a modified copy of the 6000 version. Somewhere I have the source
for the PDP-10 compiler; it came from DECUS and DEC never offered an
"official" Pascal for 36 bits AFAIK.
