The Requirement is to tag the file type for the given list of files. Using REXX, I'm able to group the files as FLAT,GDG & CLUSTER . Is it possible to further classify the VSAM cluster files as KSDS, ESDS & RRDS in rexx?

Appreciate ur help

Yes, you will need to invoke LISTCAT and parse the output

[Ramji Ram]

can u pls tell which keywords/strings should we look for in the listcat outtrap to differentiate KSDS/ESDS/RRDS?

Appreciate ur help

If the LISTCAT output includes NUMBERED, it is RRDS. If the LISTCAT output includes INDEXED, it is KSDS. If you see neither of these terms, it is ESDS. I haven't looked at enough LISTCAT output to distinguish the other types of VSAM files (yet).
