I did most of Advent of Code last year code golfing in MUMPS (running on Caché), with the additional challenge on up to and including day 7 doing without literals - that's to say no numbers and no strings. It was good fun - https://github.com/dominique-m-aoc/aoc-2025/blob/main/day03p... for day three part 1 for example. Or day 7 part 2 where the alphanumeric chars spell a story with only two nonsense words, with almost all the chars being on their own: https://github.com/dominique-m-aoc/aoc-2025/blob/main/day07p... It is a neat language but even more so a neat overall system and bag of concepts that I feel annoyed we haven't seen more of...

How do you think your code would do in GT.M or Yottadb? I understand both are open source (vs Cache).

That's cool; amazing you indeed coded in MUMPS and not in ObjectScript ;-) Caché is (was) a great technology; ironically they tried to look like a relational database in the nineties, and then eventually came the NoSql boom. How did you get to MUMPS?

		First job out of university and stuck around with it for the next dozen years, probably longer than sensible... in the context of maintaining a bag of software that got put together in the mid-80s, a substantial module of which continued to enjoy some moderate success to this day. Also, the marketing term was post-relational if I recall correctly, the funny thing about that being that it was really pre-relational at first. Also, I forgot, it was IRIS this AOC stuff runs on - the $ZV actually needs that "R" in IRIS so it knows what label to jump to... and what file mode to use... it's wonderfully cursed ;P That said, it doesn't hold a candle compared to this: https://stackoverflow.com/questions/4151554/need-mumps-sampl... which is just about the best obscured (or byte-saving rather) MUMPS snippet in existence. One thing I miss about Caché/Ensemble/IRIS is the three different paradigms for manipulating the same bits of data - the whole object layer, SQL (with pre-compiled embedded SQL an option), and the raw global access.
