Hi Friends.
I have a file consisting a list of some 20 datasets. I am using this file in a COBOL program. Then please help me to differentiate the PS & PDS datasets from the list in my program.

Thanks.

You will have to get the DSNAME using your COBOL or a REXX function.

In SAS you can get info using JFCB.
But not sure how to get this in COBOL?

JFCB can be mapped in COBOL. The relevant field for your need is probably JFCDSORG.

An example of JFCB in COBOL can be found here.

The full mapping of JFCB can be found in the fine manual.

Go thru ISPF view (3.4) and give the initial view option as Attrib , it would show/sort you with the PS/PD

You can simulate 3.4 programmatically by using the ISPF service LMDLIST.

Got a link to an example calling LMDLIST from cobol? I searched but didn't see one.

You would be invoking ISPF services from your COBOL program, and it is the ISPF manaual(s) that contain this information.

Hit the "manuals" button at the top of the page and look at the ISPF book(s).
