User exit control enables the user to run exit programs at selected points
in CICS® modules in the application domain and in other domains. The exit
program can be enabled or disabled dynamically, and useful information can
be transferred to a user work area.
This function:
- Controls which exit programs are to run at which exit points. This is
generally specified using EXEC CICS commands and can be changed during a CICS
run.
- Invokes the specified exit programs when control reaches an exit point
in a CICS module, and handles any change in flow indicated by a return code
from the user exit program.
