Description

This function controls mouse pointer movements.
It allows you to confine mousecursor movement to a region.

When an inclusion is defined, when the user tries to move the mouse pointer
out of the  rectangle, it remains stuck at the edge of the area, but is
still visible. This function should be used to restrict the range of user
choices for moving or clicking the mouse.
The screen region is defined by the bounding rectangle defined by the points
('Xleft','Ytop') and ('Xright','Ybottom').

When a mode is set, the clipping region is set for the entire screen.
If you want the clipping region to be set to the entire screen, just pass
0,0,MAXCOL(),MAXROW(),TEXT to the function.
