I already had, and the phrase "MVS subsystem" does not appear in that book. > But here's a copy/paste: > > "TSO and MVS also require that the first character of user IDs be uppercase > A - Z, # (X'7B'), $ (X'5B'), or @ (X'7C')." That says nothing about "subsystem". You appear to have inserted the word, and I'm just trying to understand why and with what meaning. > So what does "MVS" mean in this context?

I obviously wasn't clear: It's the "subsystem" part I'm asking about, not the "MVS" part. I know at least a couple of meanings of the word "subsystem" in MVS. But I don't know of any such usage that sets these additional requirements for userids. Unless you are using it with some trivial meaning like "stuff that runs on MVS that isn't UNIX or TSO and somehow, you know, does stuff with userids".
