Explanation
(MVS and VM) The named data set cannot be opened because the required DD statement or FILEDEF is missing or invalid. For an existing data set, the DD statement or FILEDEF may be correct but the attributes (RECFM, BLKSIZE) invalid. The data set may also be the result of a previous step FILEDEF pointing to the XAEREPIO RECORD file, rather than the SERLOG. SERLOG should always be used. Using XAEREPIO RECORD as input causes unpredictable results. The message will also be issued if the Data Set Name coded on this DD statement resides on Tape.
