IEFBR14 is good for such 'staging' of datasets. There are many threads (and
replies in this thread) about usage of MOD for datasets which exist or not.
You could use IDCAMS and friends to do such things if you don't mind overhead.
Or for RC usage/testing, you could use this in IKJEFT01 to determine what to do
for exist or not of datasets:
LISTDS PEST.JCL
IF &SYSDSN('PEST.JCL') = OK THEN +
DO
WRITE PESKY DATASET FOUND
SET &RC = 0
END
ELSE +
DO
WRITE PESKY DATA SET NOT FOUND
SET &RC = 4
END
Have fun. ;-)
