The same with TCBUSER. In today's environment, I use the SSVT (SubSystem Vector Table) to anchor things. And I dynamically create my subsystem if it doesn't already exist. Of course, this requires that the Subsystem name not be in use by others. I generally use something "silly". Like, for instance, BEER. (because many people like BEER). Or just use something that is unlikely to be duplicated (and essentially "meaningless"), such as O845. > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO IBM-MAIN > -- Schrodinger's backup: The condition of any backup is unknown until a restore is attempted.
