The BOX command draws a box
as per the specifications. The x y co-ordinates are for the upper left
corner relative to the values in the position command.
POSITION command is used to set the x y co-ordinates with
respect to the start position of the window.
SIZE command is used to specify the size of the box
that we need to draw.
Varying these parameters also helps to draw a line
instead of a box.
