Writing a task-related user exit program

The main function of the task-related user exit program is to translate the calling program's parameters into a form acceptable to your non-CICS resource manager, and then to pass control to the resource manager.

The calling program's parameters are described in Caller parameter lists.

This section describes the user exit parameter lists, the schedule flag word, which is used by the exit program to register its need to be invoked by CICS® management services, and register-handling in the task-related user exit program. This section also discusses the use of the CICS syncpoint manager and the CICS task manager. It also discusses some factors that you should consider if you plan to use TCBs provided by the CICS open transaction environment (OTE).
