Way to delete members not updated today?

[M Pandey]

Hi,

There is a PDS which has got around 80K members. This PDS has got a lot of I/O. I am looking for a way using which I should be able to delete all members that have been changed more then 24 hours ago. Can there be a way of doing it?

Thanks in advance.

NO!

hmm...but if we try to read the ISPF statistics, and issue a delete (which I dont know how)...can that be a strating point?

But why do you say a plain no? Any reasonin behind that? Please tell.

Not every PDS has ISPF statistics. Not every member of a PDS with ISPF statistics HAVE to have statistics -- a member added via a utility usually won't have any statistics or will have the statistics from the source (not updated to reflect the current update). And as was pointed out, if someone resets the ISPF statistics for that PDS then you lose the update information as well.
