An SRB is for running privileged code, regardless of whether the jobstep is authorized. .
The code has to be at an address that the processor can access within the target address space. That can be in the common area or in the private area. The placement is not an integrity issue. The same rules apply regardless of where the code is. -- Shmuel (Seymour J.)

Hello . Can someone please clarify this statement regarding IEAMSCHD - . "To run an SRB routine in a different address space from the scheduling code, the SRB routine must be either in a different program that is accessible from the target address space, or in the common storage together with the scheduling code." . The above was taken from Example 7 of IEAMSCHD - https://www.ibm.com/docs/en/zos/2.4.0?topic=ixg-ieamschd-schedule-srb . It makes no reference to the authorization of the target srb routine. . I would like to schedule an SRB using IEAMSCHD to a non-authorized Address Space - I would prefer not to place the target SRB routine in common storage. . I suspect its implied this is an integrity issue; as the target SRB Routine would be loaded by the Non Authorized Address Space, AND the Target SRB Routine is entered in supervisor state. . . . paul dangelo . . ---------------------------------------------------------------------- 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
