LXCURS(mode.i1.r, ix.i2.r, iy.i2.r)
This routine is used to enable, update, and disable mouse movement of
the LX color graphics display window cursor. Two types of cursor are
provided, Crosshair Cursor and Matrix Cursor. Before enabling the
cursor, a call may first be made to LXCTYP to select the cursor type
and load the cursor pattern. If this is not done, LXCURS will default
to the crosshair cursor. See the LXCTYP description for more
