The ALTER command specified the KEYS or maximum RECORDSIZE parameter with values equal to the default values chosen by the DEFINE command. The DEFINE defaults are KEYS (64 0) and RECORDSIZE (4089 4089) for non-spanned record data sets or RECORDSIZE (4086 32600) for spanned record data sets.
The ALTER command continues processing with a condition code of 4, altering any parameters other than KEYS and RECORDSIZE. Incorrect key values also prevent alteration of record size values in the same command.
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 JCL and the SYSOUT output for the job.
If the default values are not correct, run an ALTER command to correct the values.
