At times, you may want to install changes only for a single function or for a certain group of functions. This can be done with the FORFMID operand of the APPLY command. Assume that you want to install service for function JXX1234 and for all the telecommunication-related functions on your system. You first need to define an FMIDSET for the telecommunication functions. You can do this with the following commands:

SET      BDY(GLOBAL)        /* Process global zone.       */.
UCLIN                       /* UCLIN to set up
                               FMIDSET.                   */.
ADD      FMIDSET(TC)        /* Define TC FMIDSET.         */
         FMID(JXX0001       /* Include these FMIDs.       */
              JXX0002)      /*                            */.
ENDUCL                      /* End UCL set up.            */.

You can now use the following commands to install PTFs for function JXX1234 and for the functions in FMIDSET TP:

SET      BDY(MVSTST1)       /* Process MVSTST1 tgt zone.  */.
APPLY    FORFMID(JXX1234,   /* Apply for selected FMIDs.  */
                 TC)        /*                            */.
