CMS runs in supervisor state, but TSO r uns in problem state. Of course, z/OS could provide a system service corresponding to STSI. Possib ly they don't think a problem-state user should have all that information. Otherwise, why make it a supervisor-state instruction in the first place? There is, apparently, a "System REXX" in z/OS 1.8 and 1.9. Possibly that contains something like STSI(). (Or possibly I just have a good imagination.) I was curious, but I cannot download PDF manuals from IBMLink any more on my Mac, as Download Director chokes. No big loss, if you use z/OS I guess you have access to z/OS manuals. I could, of course, do it a t work, but reading z/OS manuals is not part of my job description. Alan Ackerman Alan (dot) Ackerman (at) Bank of America (dot) com
