 and  = 0 to 640, and are pixel positions along the horizontal axis. 
defines the left and  defines the right side of the window.
 and  = 0 to 480, and are pixel positions along the vertical axis. 
defines the top and  defines the bottom of the window. The reserved height
of all characters is 15 pixels so the window must be at least that high to fully
display characters. For a complete list of character widths in pixels, see
Table A–1 on page A–2. Shorter windows clip characters.
Figure 2–5 shows the coordinate system relative to the screen.
