Vista is ancient, and it's written in MUMPS, an evil twin of COBOL.

MUMPS was originally developed in the 1960s for use on minicomputers that had maybe 64KB RAM. At the time it was a lot more important to keep code size small, hence the single letter commands. Readability wasn't a concern then but it sure looks like a mess today.
It's hard to imagine it's an improvement over just the raw assembly.
For context, many (most?) other EHRs are too, though they call it M now so it sounds less disease-ridden.
No, MUMPS (or M) is a remote descendant of JOSS, an interactive language of the 1950s. JOSS has all sorts of variants (DEC's FOCAL language of the 1960s was a dialect), but I think MUMPS is the only living one. MUMPS code is mostly unreadable, as the commands can be, and often are, abbreviated to the first letter. As a result, it looks a lot like line noise.
Regardless of its many warts, Cobol cannot be accused of being unreadable. Verbose, yes.
