In DISPLAY ARRAY instructions, the setSelectionMode() method can be used to enable/disable multi-row selection.
Possible values of the mode parameter are 0 (single row selection) or 1 (multi-range selection). Other values are reserved for future use.
If multi-row selection is switched off, selected rows get deselected.
