Later than that, Morgan Stanley was still using significant amounts of
APL, albeit in its own in-house dialect, A+

https://en.wikipedia.org/wiki/A%2B_(programming_language)

My lodger at one point (around 2005 I think) got a job with MS and had
to learn A+. He was a heavy Perl user before and maintained some
official Perl packages. He was given to improvising tiny cryptic Perl
one-liners on Linux to work stuff out, calculate dates, do file
management, etc. IOW he thought in Perl.

He commented to me in the pub a year or 2 later that he realised one
evening, doing some Perl work, that after some years working in A+, he
now found Perl irritatingly verbose, and that realisation rather
shocked him. :-)

Of course this is some 15Y ago now and it may no longer be in use, but
it certainly was well past the turn of the century.
