Ed, It's called z/VSE today, and I imagine the benefits of running it are the same as they were when I ran a shop that used VM and VSE (SP2 era) -- far lower software costs, far fewer skilled sysprog staff needed to install/tune/diagnose problems, and overall just a much better TCO than z/OS for a small shop. My shop was just me and one junior sysprog, and we kept that baby humming 24/7 just by ourselves. I am surprised it still survives only because IBM has been trying to kill it and abandon all small shops for 30 years. Remember the IBM CEO (Watson Jr.? or was it his successor?) who said IBM will never stay in a low-margin business, and they have proved over and over again that they mean it. So far they've nearly managed to abandon the small ISV (Dallas "support" is a sore subject among many small ISV's), the entire academic community (with a few notable exceptions like Marist) and almost all of the small commercial shops in the USA. Europe still holds on, probably because z/VSE support and development is in IBM Germany.
