Hi,

I have changed the member xyz in the dataaset aaa.bbb. After saving the member the version is 1.18. How to see the version 1.17 of the member?

thanks,
Kavitha

There are 3 ways this is possible, but all require prior action on your part:

1) Use a library system that has versioning enabled such as SCLM. It will store your member external to the PDS and you can manually compare or recover previous versions.

2) Go to a backup of the member which was previously archived to tape or some other backup form Lookup hrecover because you may have that enabled at your site and if the timing was just right, you will be in luck.

3) If you are storing the data in a PDS, not a PDSE, AND if you have not compressed the dataset since the 1.18 was saved, then 1.17 is in the now unused portion of the PDS and you may be able to recover it using a utility like Startools or the free PDS tool from the CBT tape.

As you should have gathered from this post, there is no direct way to recover a saved member because by design, partitioned datasets are intended to have only the latest version of any given member and they do not provide a means of recovering old members (other than the specific case of #3 above).
