Vaguely related, can anyone comment on the assertions that PL/I was

I used PL/1 back in the MVT days, F level. My memory says that it
did a getmain/freemain for each PL1 procedure call.
That's correct. It was to obtain storage for non-static variables
and to set up stuff for procedure entry. The storage was given up
at procedure termination.
So reading a file
of students (30k+) you couldn't afford a procedure call in the path.
It was ok to use them during init and term (which only happened once).
This was a 360/91KK and 2314 disks...
