Oh my, just had memories of a much younger me reading these in horror back in the day:

MUMPS is standard in places which deal with Intersystems, via Ensemble (integration system) and their Cache database. An intriguing stack of technologies: an old and 100% backward compatible programming language, an object-oriented (non-relational) database with direct access from the high-level language (M; they do not like it when you call it MUMPS), and quite a number of very good software engineers having worked on this system for 30+ years.

I'm going to take a wild guess - EPIC?

First started programming in MIIS (relative to MUMPS) in late 1981. And have continued to use MUMPS/M/MSM/DSM/Cache for most of the intervening years with 4 years off for Fortran and a year or two for COBOL.

Most of the work has been with medical information systems, although the first job entailed a library information system. One of the few languages I knew of which could make a PC-AT into a multi-user machine. It also enabled a clinic to move from a PDP to a 386 and to no longer have to relegate financial batch jobs to off hours.

Will probably also continue to use AWK this year.

Oddly enough I just got a recruiter spam message for a MUMPS developer position. I had never heard of it, but I thought to myself "why would I want to develop mumps???"

OMG the memories! I did work in MUMPS while I was in college in the early 90s. I had completely forgotten about this. Thanks for that :)
