I do think I need to be more specific, since the answers so far aren't quite what I was looking for (though interesting). Probably because I am on the applications side, rather than the systems side, I have different concerns than most here. Anyway, here are some specific questions...
1) How does BMS compare to MFS. Power, flexibility, ease of use. 2) Does IMS TM have an API for "miscellaneous functions" other than just sending and receiving data? Like, does it have (or need) things that transient data queues, temp storage queues, etc. 3) Does IMS TM support VSAM, or just IMS DB and DB2? 4) All CICS transactions run inside a single address space (assuming only once CICS region, of course). I believe this to not be the case for IMS TM, but to be honest I don't really understand how IMS TM works in this regard. Is there a "control" region that dispatches "transactions" to run each in their own "message processing region"? 4a) Is the IMS TM (DCCTL?) control region the same region as the IMS DB (DBCTL) region, assuming you have a DB/DC configuration?
