How to differentiate PS & PDS files in COBOL programming

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.

I already have the DSNAME in a file. I can read the file and get the DSNAME in program. Now tell me how can i identify the dataset its PS or PDS?

In PS there is no directory block---None
But in Pds the directory block---Some value

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

But how is 3.4 coing to help him "in my program"?

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

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).
