IBM® has defined the IRREVX01 exit point to the dynamic exits facility. Therefore, you can update the exit without re-IPLing. You can associate your installation exit routine with the IRREVX01 exit point by way of any of the following:

• The PROGxx member of SYS1.PARMLIB
• The SETPROG EXIT operator command
• An authorized program issuing the CSVDYNEX macro

For example, to add load module IRREVX1A to the IRREVX01 exit point, add the following to the PROGxx member:

EXIT  ADD
      EXITNAME(IRREVX01)
      MODNAME(IRREVX1A)
      STATE(ACTIVE)

Alternatively, from the console issue the command:

SETPROG EXIT,ADD,EXITNAME=IRREVX01,MODNAME=IRREVX1A
