pv selection add	Longint	1	The new selection is added to the existing selection.
pv selection reduce	Longint	2	The selection is removed from the existing selection.
pv selection set	Longint	0	The new selection replaces the existing selection.

Example

We want to select both the column and the row of the current cell.

 C_LONGINT($Column;$Row) //To get coordinates

 C_LONGINT($ColSelect;$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

    PV SELECT ROWS(Area;$Row;$Row;pv selection add) //Select it

 End if
