Changing the remote program name

The user exit is passed the default program name that CICS® works out by using the rules that are shown in Two ways to implement DPL in your application program. If the request is local, this is the name of the program that is to be run on the local system. If the request is remote, this is the name of the program on the remote system.

Note: If the user exit returns a null string in the UE_Dplprog parameter, an abend and message is issued.
