Returns the window coordinate equivalent to a viewport coordinate, as defined
by the WINDOW statement, or vice versa.
 
PMAP (startcoordinate#, n%)
 
    ■ startcoordinate#    A window or viewport coordinate.
    ■ n%                  A value indicating which coordinate is returned:

                          Window x coordinate     0    Viewport x coordinate
                          Window y coordinate     1    Viewport y coordinate
                          Viewport x coordinate   2    Window x coordinate
                          Viewport y coordinate   3    Window y coordinate
 
Example:
    'This example requires a graphics adapter that supports screen mode 1.
    SCREEN 1
    WINDOW SCREEN (0, 0)-(100, 100)
    PRINT "Logical x=50, physical x="; PMAP(50, 0)
    PRINT "Logical y=50, physical y="; PMAP(50, 1)
