                 --    ---------------------------------
                 0     The current viewport x coordinate
                 1     The current viewport y coordinate
                 2     The current window x coordinate
                 3     The current window y coordinate
 
    - (x%,y%)    The coordinates of the pixel that POINT checks for color.
                     If the coordinates are outside the current viewport,
                     POINT returns -1.

    'This example requires a color graphics adapter.
    SCREEN 1
    LINE (0, 0)-(100, 100), 2
    LOCATE 14, 1
    FOR y% = 1 TO 10
        FOR x% = 1 TO 10
