A lot of people program in ALGOL 60
There is a lot of programming done in ALGOL 60 on Burroughs machines (now Unisys MCP machines). Burroughs extended the language with IO, some an extension of FORTRAN-style IO, but most programmers did their own direct formatting, since the FORTRAN IO was interpreted and slow.
I believe Burroughs ALGOL was based on Elliot ALGOL. I later worked with another Burroughs guy who developed a language based on Elliot ALGOL for the Apple II. This was at a company called Netcomm in Australia.
Actually Don Knuth wrote one of the first Burroughs ALGOL compilers on a summer break as a student. It was on the B200 (from memory), but it predated the B5000 ALGOL compiler.
Burroughs ALGOL is a really heavy-duty systems language that makes C look like the toy that it is. It is a shame that C has effectively killed language development. If ALGOL or its next generation (ALGOL-68, ALGOL-W, Pascal, CPL, etc) had continued, we’d probably have pretty solid languages by now, rather than the rather flimsy C.
