Hi Jay,

>I set m.RecNo to the current record number. Then a filter condition happens where that particular record number is no longer available. What is the best way to get to the next previous record number that is available?
LOCATE RECORD m.RecNo
IF EOF()
  SKIP -1
ELSE
  SKIP +1
  IF EOF()
    SKIP -1
  ENDIF
ENDIF
This moves to the next valid record, or if such one doesn't exist, to the previous one. By moving to the next first, instead of the opposite way, you get one positive effect on the UI. If the table is shown in a list, the highlighted row now stays at the same place. If you would move to previous record first, the highlight would move upwards in most cases.
