Algol 60, that is. It was used as the inspiration by
just about
everything that followed
I've just remembered that the Algol (probably Algol-60, but the manual
doesn't say) interpreter used for the programming languages course at MIT was
adapted from the Delphi (a homebrew PDP-11 OS used at MIT) version, to a
version that would run under Unix V6. So it should be runnable under any
PDP-11 emulator.
I _think_ I have that on those backup tapes I'm trying to get read, so maybe
someday (it's a pity none of that MIT Unix stuff seems to have escaped into
preservation, at least, so far) it will be widely available.
They had a BCPL compiler for the PDP-11 that ran under Unix, too. Ditto about
'on the tape'.

Mostly I write SNOBOL4 throw away programs for textual
transformations.
Huh, that's what Regex-Replace is for! ;-)

There?s DECUS ALGOL, which is essentially a PDP-11 version of Burroughs Extended Algol.
It generates bytecode which even looks somewhat like B5500 machine code. I still have a
copy, though I need to do some work to find the correct sources and build procedure for
the runtime support code.

Neat! I'm a big fan of RSTS/E, are you able to make your tweaked
version available?

I have a BCPL compiler for RSX here... Never used it myself, so I don't
know how good/bad it might be. I think it came from the DECUS library.
