I think the prefix is remembered across TSO sessions, and it is stored in the TSO segment of RACF. However, it is stored at LOGOFF time, so interim changes are not recorded. Lennie

As such, almost any program running in the TSO session can change it. I don't think that any of RACF, ACF2 or TSS can protect you against that. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
