BTW my Dad was one of the first users of the original 2 cassette MCM-70 in
the US. We had one at home, along with a selectric terminal that we used
(from 1969 on) to access APL on a mainframe. Fun days. His MCM machine is
on display at CHM.

I wrote several different kinds of simulator, one of which generated APL
code on the fly that was then executed... plus a database-or-two.
I've been actively collecting APL memorabilia and books for years now...
if I could find an MCM/70 it would be awesome...

The second or third hit when I search for "Knuth" is this one:
. It's not just about APL, it actually has a downloadable copy of the

Nice. I'll have to give it a try.
I recall Neil Lincoln (he of CDC/ETA) relating that he taught APL to his
kids and his wife (APL was pretty much a natural for the STAR) as a
first programming language.
I took some time to learn it fairly well, but never really had any
opportunity to use it much, so it's gone into the memory dustbin of old
never-used languages of my brain.
A co-worker back when would never use the name of the book or the
abbreviation. He always referred to it as "that Iverson language" or
And it's comparatively easy to write short, perfectly opaque code in
APL; probably more so than other common languages.
