After receiving a set of SYSMODs, the next step is to apply them to the target libraries. To do this, the SET command must specify the target zone associated with those libraries. In this example, the SYSMODs are being installed into a target zone named MVSTST1 that represents a set of test libraries. The following commands are required to apply a SYSMOD:

SET      BDY(MVSTST1)       /* Set to process MVSTST1.  */.
APPLY    SOURCEID(PUT0701)  /* Apply service level      */
         GROUP              /* with group to pick up
                               previous resolved
                               exception SYSMODs.       */.

The result is that all PTFs that were received and assigned a source ID of PUT0701, and that are applicable to the functions in the MVSTST1 target system, are applied.
