        reference:

        cLast := "Winston"

        //
        DBUSEAREA( .T., "DBFNTX", "Sales", "Sales", .T. )
        DBSETINDEX( "SALEFNAM" )
        DBSETINDEX( "SALELNAM" )
        //
        DBUSEAREA( .T., "DBFNTX", "Colls", "Colls", .T. )
        DBSETINDEX( "COLLFNAM" )
        DBSETINDEX( "COLLLNAM" )
        //
        DBSELECTAREA( "Sales" )      // select "Sales" work area
        //
        IF ( Sales->(DBSEEK(cLast)) )
           IF Sales->( DELETED() ) .AND. Sales->( RLOCK() )
              Sales->( DBRECALL() )
              ? "Record deleted: ", Sales( DELETED() )
           ENDIF
        ELSE
           ? "Not found"
           Colls->( DBCLOSEAREA() )
        ENDIF
