The requested module.

System action

System programmer response

An incorrect Z-byte should not occur. Search problem reporting databases for a fix for the problem. If no fix exists, contact the IBM® Support Center.

The DCB is not in protected storage, so it is possible for a problem program to overlay the Z-byte with an incorrect value. Attempt to determine how the byte was overlaid.
