Hi All,
Can anyone please let me know the JCL utility to find a dataset exists or not.I think we have a utility that gives a RC of 1 if the DS exists and a zero if it does not.It will be great if anyone can help me out with this.

Thanks,

Hi,

I think LISTC utility(If awailable on your shop) can be used to check whether the dataset exists.

Example pseudo code can look like this.

//EXIST1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
LISTC ENT('SOME.DATASET.NAME')
// IF RC = 0 THEN
//* executes when dataset exists
??. more JCL here ???.
// ELSE
//* executes when dataset doesn't exist
??. more JCL here ???.
// ENDIF

Corrections welcome.
