If you are accessing an ASCB other than your home space, they can be safer to use. If you are disabled for I/O and External interrupts, and then validate the ASCB by locating via the LOCASCB macro, the ASCB/ASSB storage cannot be freed while you remain disabled. The fields pointed to by ASCBJBNI and ASCBJBNS are located in an extension of the CSCB, and disablement does not prevent that storage from being freed.
