Crytolog magazines are always interesting.

One thing that intrigued me were the mentions of the POGOL language. There seem to be no mentions of it on the internet, which makes me suspect it is either an arcane language specific to a 3-letter agency. That agency may either be IBM or NSA.. both seem equally as likely.

There were a lot of ALGOL variants around in the 1960s & 70s if you look at the Wikipedia page for ALGOL, including one called GOGOL for the PDP-1. My first guess would be that POGOL was an ALGOL-a-like for the IBM-360, perhaps developed internally by the NSA?

I would assume an ALGOL variant.

Given that this was in '78 (which is quite late in ALGOL's lifetime), it's possibly the "P" referred to the P-porting kit for Pascal[1]?

That's speculation of course, but the ALGOL name variations generally did mean something.
