Remarks
DBClearFilter() performs the same function as the SET FILTER command with no expression specified.
For more information, refer to SET FILTER.
By default, this function operates on the currently selected work area.
It can be made to operate on an unselected work area by specifying it within an aliased expression or by calling the overload that accepts a workarea parameter (a workarea number or alias ).
Tip Tip
Logical records: DBClearFilter() affects the logical visibility of records in a work area.
For more information, refer to DBSetFilter() and the SET FILTER command.
