I think you are hinting about what sort of things the recovery routines actually recover from. I simply want to run VSMLIST to get the virtual storage addresses then upon request read the memory there and be done. :>I got this far, and it runs to completion, but I can't tell if it worked :>or not.

I saw it in one or more of the examples that I looked at and thought that it needed to be there. :>SRBRTN DS D >> What will be in that doubleword? I have now: SRBRTN DS 0H I've since changed it to DS 0D. I put it there because someone advised me to start my code on a double word boundary. The other stuff was my failed attempts to copy my code to the CSA which seemed a very strange thing to do. Then I thought about von Neumann and it was ok after that. :>No abend, nothing.

I scheduled it into the address space of another TSO user id because I wasn't sure what would happen if things went wrong and I wanted to be able to monitor what was happening. I managed to corrupt the TCB of the TSO session. But that's just luck I think. I could have just as easily corrupted the operating system. ---------------------------------------------------------------------- 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
