If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the logrec data set error record, the job control language (JCL), the program listing, and the assembly listing for the job.
