Here's a DFSORT/ICETOOL job that will do what you asked for. Note that there's a system restriction related to the use of referback for concatenation with multiple volumes, so you might want to have the SELECT in one ICETOOL step and the SORT in another if that's a concern.

The solution worked fine. I see the methodogy of splitting out the last record of each userid set, flagging it, and sorting it back together with the non-selected records. Thank you for all your invaluable advice on this problem as well as all the others.
