These commands draw filled or unfilled rectangles on the screen. The
coordinates of the two opposite corners are specified by x1,y1 and x2,y2.

BOX draws an unfilled rectangle.

PBOX draws a filled rectangle.

RBOX draws an unfilled rectangle with rounded corners.

PRBOX draws a filled rectangle with rounded corners.

Example:

    BOX 20,20,120,120
    RBOX 170,20,270,120
    x=150
    DEFFILL 1,2,4
    PBOX 20,20+x,120,120+x
    PRBOX 170,20+x,270,120+x

--> An ordinary rectangle is drawn, followed by one with rounded off corners.
    Finally both shapes are drawn again but with a different fill pattern. A
