 Prototype

     ERRCODE setFilter(
                             AREAP wa,
                             LPDBFILTERINFO lpdbFilterInfo
                          )

 Arguments

     wa is a pointer to self.

     lpdbFilterInfo is a pointer to a structure containing information
     about the filter condition set for the work area.

 Description

     setFilter() sets a table filtering condition for the work area
     referenced by wa.

 Default Behavior

     setFilter() sets the wa->dbfi to the filter expressions held in
     lpdbFilterInfo.

 Implementation Notes

     .  Prior to setting the new filter, setFilter() must perform a
        clearFilter(), which is defined as releasing the items held by the
        wa->dbfi structure.
