Hi
Do we have any command to retrieve file attributes for a TAPE files.
I have a requirement to check if the created output file from REXX whic will be on Tape exists or not ?
If exists I need to create the file with another name..
Thank you

Not that I know of, no. Usually details for data on tape have to be retrieved through your tape management system.

Define exists
Exists physically or exists as a catlog entry ?

Presumably your 'rexx' created the tape in batch as it is highly unusual to use tapes in TSO/ISPF.

Hello,
Do we have any command to retrieve file attributes for a TAPE files.
Which attributes?

Have you verified on which media the file resides?
Your best source for this information is your Tape Storage Management people.

Hi All
Thank You for your replies
I have tried LISTC ,
"LISTC ENT('"STRIP(DSN)"')"
If RC=0
Then the DSN given is cataloged.I wanted to know if the DNS(in Tape) already exists or not.
Thank You

LISTC will tell you if there is a catalog entry, but that is not proof the dataset actually exists on the tape volume. Only by actually opening the dataset can you prove the dataset exists on the tape volume. Using the tape management system is not really proof the dataset is really there.

Especially true with VTS. In the day of physical tapes, unless the tape had since been written on the data would still exist, but with VTS and depending on the setup at your site, the tape may be come totally unusable the very second it is returned to the scratch pool.
