To install multiple functions in a user exit routine, do the steps shown in
Installing Control Program User Exits and the following:
- Define a bit in IUXEQ for each function you want to use in a user
exit. The IBM-supplied copy of IUXEQ has bits defined for vendor
products that are installed in user exits.
- Update the user exit code in CUSR with a stub routine that will link to
each function defined for use by the exit point. The stub routine can
be built by coding a sequence of UXMAC macros.
- Note:
- The order of UXMAC macros dictates the order in which functions in an exit
will get control.
- Provide a program to activate or deactivate functions in the user exit
using the UXCMC macro. Define these functions in the expanded format of
the parameter list, UX1PL.
- Note:
- Use this activation or deactivation process for dynamic and nondynamic user
exits.
