PV New offscreen area Longint

Function result Longint 4D View area

The PV New offscreen area command builds a 4D View area in memory and returns the reference to this area. This reference should be passed in any 4D View command requiring a reference to an area.

When you no longer need the area, do not forget to clear it using the PV DELETE OFFSCREEN AREA command in order to free the space occupied in memory by the area.

This method allows copying the content of a template so that you can copy it in your screen area.
