The well-known place to start is GPSAM on the CBT site. http://cbttape.org/cbtdowns.htm GPSAM (file 290 and another version in file 648) is indeed remarkable in that it's 45 years old, and the code and doc are still 99% valid on current z/OS. To say nothing of the high quality of Howard Gilbert's short but to the point doc. It's entirely possible that GPSAM may already provide the infrastructure for what you want to do, though much of its initialization would be done differently if written today. (Actually I self plagiarized the above from a posting I made here several years ago.) If nothing else, read Howard Gilbert's doc on how this kind of subsystem works. It certainly doesn't discuss OBTAIN, and I have no idea if the OBTAIN function includes a subsystem call to gather info, or if it's a conceptually wrong thing to be doing. I suspect the latter, but if OBTAIN works with your vendor subsystem...
