Because it's dead-simple to parse? Remember that not all machines back then had hardware call-stacks.

Tell me you would have come up with a Pratt parser yourself (or even a parser generator).

Simplicity of implementation?
Not just simplicity-the original implementation was for a very resource-constrained 1960s minicomputer, where a more complex implementation would have slowed the system down even more and left less memory for running the actual business application

PSA: POSIX shells (bash etc) do the same thing for && and ||. `true || false && false; echo $?` will be 1, not 0, because it evaluates `true || false -> true; true && false -> false`, not `false && false -> false; true || false -> true`. Don't assume like I once did that they have precedence like they have in C etc :D

#16Part-time MUMPS programmer here for a health system in NYC. I still love writing in it. The rates are way better than other eco-systems (e.g. Python, Java, blah blah) , probably because the eco-system isn't diluted with low-wage workers from India/China. This is because 95%+ of Epic/Ex-Epic employees are American. I would even argue it is the patriotic language of choice due to that reason.
Expected pay of 85-120/hour, which pays way more than my full-time job. It's a fun language to write in, and the adrenaline rush you get when you get a triple index loop working is awesome.
Also random fact - according to Epic HR , the average college GPA of Epic employees was 3.5, which is probably the perfect formula in hiring loyal corporate servants. I always thought it was weird that I had to apply with my transcripts and resume.

It’s definitely easier to parse, but you can use shunting yard to do operator precedence parsing using very little extra memory and no recursion. I feel like the language is just poorly designed.

I'm not sure I love paying it with worse health services though. My city has sunk almost a billion dollars into a dysfunctional Epic pile of MUMPS.
But I guess it's nice to see the healthcare software disgrace works well at least for some.

Would reverse Polish notation be just as easy to parse and interpret?

Makes me curious about getting MUMPS to run locally on a Mac. I had great fun with it 15 years ago.
