No service that I know of tests for "possible ways". They always look for the PSW. It is expected and assumed that authorized programs follow expected conventions. If they do not, then they get what they get. You might view that as a problem, but no one will be changing any code if someone brings that up as a problem. And I'll be glad to admit that there likely is no particular place where one can go to look up "the conventions" as to which instructions are appropriate to use (or, more important, not to use) Peter Relson z/OS Core Technology Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
