As I understand it, it's like Lua, except that variables aren't declared, and they're in a global namespace. And they're limited to 8 characters long. And if's and loops are limited to single lines (that are probably limited in turn to 80 or 60 characters - whatever their punched cards were eh?)
Basically unusable for large systems. But used for them anyway.
Any shop that's forced to use Mumps should write a compiler for a better language that outputs Mumps, and convert their Mumps code to that better language. It would take a much shorter time than maintaining Mumps code.
