Thanks Larry, I found it after I sent this to the list.  But one thing
now bothers me; when I recalculate to a lower retention period (from 6
weeks to 2 weeks) does it happen immediately?  And does it prune the
catalogue's?  I didn't really noticfe any change in my catalogue
filesystem after recalculating 3 classes.  Here's the line I used:

bpexpdate -recalculate -ret 1 -class <classname>

Thanks.
