Unstring was his friend, I would guess. Nothing in COBOL is recursive.

Moving to COFF where this probably belongs because its less UNIX and more

I can easily believe that PL/I was written in PL/I. While at Tandem,
I met Don Nelson, apparently an important member of the COBOL world.
He was, of course, responsible for our COBOL compiler (which, again
I'm told, had quite a good reputation). Don told me that he had
written it entirely in COBOL.
Now that's a whole different level of difficulty.

What language were the PL/I compilers written in?
I don't know about anyone else, but the VAX PL/1 front-end was bought by
DEC from Freiburghouse (??SP??) in Framingham, MA. It was written in PL/1
on a Multics system.
