I think if you are listing a level of data sets with LISTC you use LISTC LEVEL(dataset name) Then it should produce an RC=0
I don't have a system to check this, but I think it is correct.

I'm aware I can use IDCAMS to check a dataset's existence via //STEP001 EXEC PGM=IDCAMS //SYSIN DD * LISTCAT ENTRIES(DATASET.NAME.FLATFILE) //* // IF (STEP001.RC NE 0 OR ABEND) THEN .... But IDCAMS doesn't recognize relative generations so this method doesn't work for a GDG. That is, //STEP001 EXEC PGM=IDCAMS //SYSIN DD * LISTCAT ENTRIES(DATASET.NAME.GDGBASE(0) ) //* // IF (STEP001.RC NE 0 OR ABEND) THEN .... Is there some means to do this without creating a REXX exec to process the check? I'm drawing a blank.
