Changing the program name

For transactions defined as DYNAMIC, on invocation of the routing program the DYRLPROG field in the communications area contains the name of the initial program associated with the transaction to be routed. If you decide to route the transaction locally, you can use this field to specify an alternative program to be run.

For example, if all remote CICS® regions are unavailable and the transaction cannot be routed, you may want to run a program in the local CICS terminal-owning region to send an appropriate message to the user.
