User exit problems

 

The interaction between the channel programs and the user-exit programs has some error-checking routines, but this facility can only work successfully when the user exits obey the rules described in Further intercommunication considerations. When errors occur, the most likely outcome will be that the channel stops and the channel program issues an error message, together with any return codes from the user exit. Any errors detected on the user exit side of the interface can be determined by scanning the messages created by the user exit itself.

You might need to use a trace facility of your host system to identify the problem.
