A user attempted to issue a MODIFY CATALOG,END or MODIFY CATALOG,ABEND to end a catalog service task. The system cannot end the task however, because it is performing a necessary function in the user address space.
The system ends the command.
Enter the MODIFY CATALOG,LIST command to obtain the name of the user job associated with the catalog service task. Enter the CANCEL command to cancel the user job. The CANCEL command also ends the associated catalog service task.
