Comments

  • Required service for z14 exploitation.
    This APAR includes updates to z/OS Supervisor control and other
    components for the Guarded Storage Facility introduced with
    z14.

     Add documentation for IEAGSF service.
    
     IEAGSF is documented in z/OS V2R3 documentation at URL:

      ..
      MACHMIG
       Identifies one or more facilities that you do not want z/OS
       to use at this time because migration to another processor,
       z/OS release, or both is underway.
       Code the MACHMIG statement as described in Table 39.
