There was a bit of discussion offline about SPF and its origins, Can
you shed some of your knowledge from whence it came?
It started[1] life as structured programming facility (SPF). At some
point it became a program product, under the same name. Then it became
System Productivity Facility, then Interactive System Productivity
Facility (ISPF). I don't recall the original (FDP or IUP?) progam
number, but two early program product versions were:
TSO - 3270 STRUCTURED PROGRAMMING FACILITY (SPF), 5740-XT2
TSO 3270 DISPLAY SUPPORT AND STRUCTURED PROGRAMMING FACILITY (SPF)
VERSION 2 SPECIFICATIONS, LIC PROG 5740-XT8
There were also VM versions for CMS users.
[1] There may have been an internal version under a different name
Thanks... this is the middle ground we had a discussion on.
One point that does need clarification (to me) SPF (original) was it
a IBM FDP. I ask this as maybe the details over the years have gotten
lost.
The "way" I remember it that IBM developed it on a system in Chicago
and my SE (we were in Chicago) went over to look at it and he came
back excited about the product and had a 3 page folded IBM paper on
it (wish I had kept it now). We ended up picking FSE as it was a lot
cheaper and used less resources (CPU) which we were always short on.

ps: I know the term "structured program facility" was a hot topic but
I think it also had a name of system programmer facility as well.
