Explanation
A utility program was supplied a restart data set that was not of proper format.

Processing continues.
Programmer response
If a RESTART was not required, remove the DD statement DFSURSRT. If a RESTART was required, ensure that the DD statement is correct, and resubmit the job. If the DD statement was correct, the checkpoint data set has been destroyed and cannot be used. RESTART the job from the beginning.

2, 3, 8, 36. Also, if running under the Utility Control Facility, rerun the job with a FUNCTION=OP,MSGNUM=377 control statement in the DFSYSIN data set. Supply a SYSUDUMP DD statement to this step.
