The Wikipedia article on Pick[1] has some good background info. This stuff is pretty "old school" but is still in use in places.
Funny thing... I did an A.S. in Computer Programming back in the early 90's and the community college I attended had a Prime mainframe in the IT department, and ran Pick databases. I did some "work study" stuff with the IT manager there, but never really had a chance to get deeply into the Pick stuff. I was always curious about it though, so seeing this story (and this comment) brings back memories...
