Try
lnRecNo = RECNO()
SET FILTER TO < whatever >
*-- attempt to restore the pointer
<B>LOCATE RECORD lnRecNo
IF NOT FOUND()</b>
  *-- record not part of filtered set, so we
  *-- issue a LOCATE which will select the first
  *-- record in the filtered set
  LOCATE
ENDIF
>Doesn't work either.... I checked RECNO before and after FILTER call with the "current" record NOT being in the new filter set - RECNO() does not change.
