Thanks for the feedback. No joy finding said SAS job. 

Seems I've exhausted any solutions from this group. I'll open a ticket with IBM 
and see if there is anyone else who might have a solution.

Again, thanks for all the input.

Subject: Re: Deleting old HSM backups

I am trying to remember....
Somewhere in the last 40+ years there was a SAS job that altered the MCDS (or 
was it the BCDS)?
It ran through the entire CDS in a few minutes and then you would run expirebv 
and magically all those datasets would evaporate.
I am trying to remember where the SAS job came from but cannot say for sure but 
it might have come from Berry Merrils(sp?) collection of SAS jobs, I just do 
not remember sorry. But somewhere out there is a a SAS job that marks the HSM 
cds's properly for clean up.
