I am lookin through a list of file names to find out if they exist or not by doing a sysdsn in REXX.

My list also contains some tape dataset and sysdsn is taking few minutes for them.

Since I am not interested in tape datasets, is there a to identify if it is a tape dataset or not.

Dibakar,

Did u try using LISTCAT entries (from REXX)? Actually it is a bit better than SYSDSN. For example if a dataset is migrated, and if you use SYSDSN on that, it issues a automatic recall on the dataset. Instead if you use LISTC you can easily find whether the dataset exists or not without recalling it. I hope LISTC will be helpful even to check the existance of tape datasets.

Thanks,
Phantom

When LISTCAT shows a DEVTYPE like x'78048081', look for this:

xxxx80xx is tape
xxxx20xx is DASD

Regards,
Bill

I beleive I faced same problem with LISTC, don't remeber exactly now. But my problem was solved when I was informed that I don't have to bother about production datasets since all these tape datasets were production datasets.
