I don't really know anything about PICK. I worked at a place for about 4 years that was running a PICK emulator (uniVerse?) on HP-UX. It was an HMO that did their claims processing on it and the app was written in PICK BASIC (at least that's what I thought it was called). I worked on the DSS stuff (which were extracts of the PICK files into Sql Server) so I didn't play much with the emulator too much. Didn't really seem that bad, I occasionally had to do some command line scripting and I did set up a few tables/scripts, even some applets, but was by no means an expert.
Years ago when Windows 3.10 came out and I wrote my first database application with the Win16 SDK I thought, this GUI crap will never catch on for head-down data entry. Shows how much foresight I had, doesn't it?
