row	Longint	Cell row number
action	Integer	Select action

Description

The PV SELECT CELL command selects the cell located at the intersection of column and row.

The action parameter allows defining the selection action that you want to execute when a selection of cells already exists: you can create a new selection, add the cell to the selection or delete the cell from the selection. action is defined in PV Selection action constants:

Constant	Type	Value	Comment
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 the cell E2. The selection action will depend on the context (already selected cells):

  `Arrays defining the existing selection:

 ARRAY LONGINT($Left;0) `Left-hand cell column numbers

 ARRAY LONGINT($Top;0) `Top cell row numbers

 ARRAY LONGINT($Right;0) `Right-hand cell column numbers

 ARRAY LONGINT($Bottom;0) `Bottom cell row numbers

 

 PV GET SELECTED RANGES LIST(Area;$Left;$Top;$Right;$Bottom) `Get selected ranges if any

 

 If(Size of array($Left)=0) `No current selection

    PV SELECT CELL(Area;5;2;pv selection set) `Set E2 cell as current selection

 Else

    PV SELECT CELL(Area;5;2;pv selection add) `Add E2 cell to current selection

 End if
