There was a company her in Scranton, PA that did a very complex

It's a different world from BASIC, for sure.
Neil maintained that its strength lay in thinking about things in a
non-scalar way.? I'll give him that--programming on STAR, where a scalar
was treated by the hardware as a vector of length 1 (and thus very slow
because of startup overhead) certainly led you toward thinking about
things in vector operations, just like APL.
Here's the APL*STAR reference manual:

Thank you for that!
You are right.? At the time, it simply never occured to me that anybody
would use it for anything other than matrix processing of scientific data.
(MY view of the elephant)
Yes, I suppose that somebody of sufficient skill COULD write accounting
software with it, . . .
But why?
And, one of the advantages of COBOL for business programming was the
possibility of checking somebody else's code.? APL was intrinsically
obfuscated code.
I have known many APL programmers who would not agree with this. When
I was doing COBOL and Fortran at West Point, NY we had an intern from
Marist College. APL was their common instructional language and the
only one our intern knew when he started.
It was at West Point that I learned APL and I have since run it on
everything from a Micro to a mainframe. Still have a version that
runs quite well on my TRS-80's.
