This message is issued when the attempt to switch to a new broadcast data set fails. TSO/E received an unexpected return code from ENQ processing.
The current broadcast data set remains active.
Issue the command again. If it continues to fail for the same reason, contact the system programmer.
Look up the return code for the ENQ macro in the z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG.
