 C_INTEGER($ColSelect;$RowSelect) `To know if the column/row are already selected
 
 PV GET CURRENT CELL(Area;$Column;$Row) `Getting current cell coordinates
 $ColSelect:=PV Is column selected(Area;$Column)
 $RowSelect:=PV Is row selected(Area;$Row)
 
 If($ColSelect=0) `The column is not selected
    PV SELECT COLUMNS(Area;$Column;$Column;pv selection add) `Select it
 End if
 
 If($RowSelect=0) `The row is not selected
