NAME
  WINDOW Statement

SYNOPSIS
  WINDOW [[SCREEN] (x1!,y1!)-(x2!,y2!)]
      o SCREEN       Inverts the normal Cartesian direction of the y screen
                     coordinates so that y values increase from the top of the
                     screen to the bottom.
      o (x1!,y1!)    Logical coordinates that map to the upper-left screen
                     coordinates of the viewport.
      o (x2!,y2!)    Logical coordinates that map to the lower-right screen
                     coordinates of the viewport.
      o WINDOW with no arguments disables the logical coordinate system.
      o Use the VIEW statement to change the size of the viewport.

DESCRIPTION
  Defines logical dimensions for the current graphics viewport. Use the WINDOW
  statement to define your own viewport coordinate system.

  Example:
      'This example requires a color graphics adapter.
      SCREEN 1
      FOR i% = 1 TO 10 STEP 2
          WINDOW (-160 / i%, -100 / i%)-(160 / i%, 100 / i%)
          CIRCLE (0, 0), 10
      NEXT i%
