Hi David, The Read Block ID command (x'22') is documented in IBM 3490E Hardware Reference, e.g. GA32-0219. If you wish to avoid EXCP, you might be able to use the NOTE macro with TYPE=ABS operand. See z/OS DFSMS Macro Instructions for Data Sets, SC26- 7408. I wonder about your requirements though. - Are you writing to real 3490E cartridges? The same ones that I believe will no longer be manufactured in only a few weeks from now? (If so, I know where there are 10,000 still shrink-wrapped on a raised floor...let me know!) - Isn't tape duplication that "cannot have multi-file tapes" (or did you mean multi-volume) of limited value? I respectfully disagree with Mr. Witt that this is easier with 3590 and above, because AFAIK you must first obtain a licence from IBM for 3590 S/390 Hardware Interface Information, or reverse engineer the "new" commands. If you already have the licence, then yes it's easier. (I suppose someone could accidentally give you the information, but that doesn't happen).
