Subject:      seeing ahead

I've seen this a long time ago, but can't rememeber where or when.  We
have a need to see if the next record in a flat file contains duplicate
information.  If so, we want to keep all the records pertaining to that
information, and delete those that don't have duplication.  I've seen
something similar to LAG, but in reverse, awhile ago.  Anyone have an
idea?  In the meantime, the only other way that I can think to do this
is to do duplicate reads via an input, or to get all the info
initially, then do a sort and a if not first.....

Thanks in advance for any help.

Regards,
Pat Flickner
