Then why even bother with the SFLSIZ>SFLPAG?  If anything, your users are
confused as to when their options are "lost" or "kept".  Or maybe they've just
gotten to the point where they never page the subfile if they've got an option
on the current page.

As per my response to Paul, you may be interested in an article in the September
