I see your "dumb question" and raise you a few more :-) 1 CPU. I can answer that one. I don't know how to answer the TCB question; My z/OS colleague says "six usually". It's a single-threaded application that reads a file, does some stuff to it (encrypts some of it), then writes it back out. Nothing fancy. If it did have multiple CPUs, then I could see wall-clock being less than total CPU. But the total at the bottom shouldn't be less than one of the steps anyway, should it? ...phsiii <snip> CALL. Double check the SMF exits (I think those are the ones that put out this info). There could be a logic error in it (arithmetic or failed to clear some getmained storage -- a bit of that going around I hear). Otherwise, I'm at a lost as well. (Oh, and someone already suggested which exit).
