Coding a program to be started by the CICS sync point manager

An exit program must “schedule” the sync point manager by setting the sync point manager bit-mask in the schedule flag word. The bit-mask must be set after every piece of recoverable work to ensure that the CICS sync point manager calls the exit program during sync point processing. The identification of the current unit of recover, or unit of work, is addressed by the 8-byte field UEPURID. This field is available on all invocations of your exit program in which recoverable actions are possible, for example, application calls and subsequent sync point manager calls.
