I saw a video about the 360 architecture, and I noticed the same guy did a couple videos on the PDP. One click led to another, and it turns out he did some videos about MUMPS.
MUMPS, plays a small part in my early (late 1970s, early 1980s) attempts to find work on DEC PDP-11 computers. Because at the time I would see MUMPS jobs associated with the PDP-11, and I saw quite a few PDP-11 jobs looking for expertise in MUMPS back then. And that is mostly the extent of my knowledge of MUMPS. However I always was somewhat curious about it. So the above video, lead to this link. And some more googling lead here.
Evidently it’s still a thing.
So it appears it’s a database and/or a language, sometimes called M. Some sites that talk about M don’t even mention MUMPS, but some do!
More googling and I found this… somehow related to MUMPS.
I have enough on my plate right now, with Go and REXX.
