IDCAMS should work fine when you need to know if a given dataset exists or not:
LISTC ENT('A.B.C')
If A.B.C does not exist, you would get a rc=4, and you can
execute the next step conditionally with the IF-THEN-ELSE capability.
Likewise, if you want to check if a dataset is empty, IDCAMS is your friend:
REPRO IDS('A.B.C') OFILE(DD1) COUNT(1)
If A.B.C is empty, you receive a rc=4.
