I'm doing some kind of research on one of my prod JCLs. In my JCL(calls a proc inside it), there is a DSN concatenation, the DSName being the latest generation of a same file say ABC.PQR.XYZ(0), DISP=SHR. When I give PREP it says GDG index not built ONLY for the last two datasets which are dummied out. Is the below DD DUMMY code valid?
FYI...The job runs fine in production.

When I remove DSN='', it doesn't show me the error msg on PREP. I cannot test it, so pls clarify. Thanks in advance.

Thanks Dick.
hmm.....Just wondering why my PREP is showing that error only for those dummied datasets eventhough the GDG name is the same in the entire concatenation.....Is that something to modify in JCLPREP admin side?

Hello,

It may simply be a warning from PREP reminding that the dsn will not be used. . .

Suggest you submit the job with typrun=scan and see if the system accepts this or throws an error.
