I've recently come across a high level language called PL/65 - It seems Atari based though. Looks like a combined suite of editor and compiler.

Some details here:

https://atariwiki.org/wiki/Wiki.jsp?page=PL65

But no sign of the sources - anyone here know about it?

Cheers,

-Gordon

Interesting, kinda reminds me of a line number-less BASIC with some Pascal tossed in (not surprising since Pascal and PL65 are both derived from ALGOL).

I'd love to try porting this if only we had the source.

Some of https://www.google.com/search?q=pl65+6502 maybe?

I don't think this Atari PL65 is a PL/1 derivation like the PL/M language used to write CP/M (and later a full PL/1 compiler) or Rockwell's PL/65.

I've been looking for PL/65 too but no trace it remains other than in magazines and journals.

It might be worth searching PDP-11 archives as it was available as a cross compiler. Not tried that yet.

Source for Atari PL65?: https://atariwiki.org/wiki/attach/PL65/pl65src.zip

Source(s) for Rockwell PL/65?: https://github.com/assinie/PL65/tree/master/src/pl65

These languages look very similar in some respects.

The Rockwell PL/65 repository appears to be an attempt to reverse engineer this disassembly

into PL/65 source code but looking at the listing it looks hand coded so this could be tricky.
