Running in (any) system key allows the program to overwrite any storage in that system key. Every bug in that program puts part of the system at danger. APF authorization is much preferred, IMHO, since you can switch in and out of the authorized mode (supervisor state, or system key), only for as log as absolutely needed. If you run in system key via PPT, you have to stay there. I haven't tested of RTFM, but I think you would not be able to return to system key once you left it. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
