NAME
  PMAP Function

SYNOPSIS
  PMAP (startcoordinate#, n%)
      o startcoordinate#    A window or viewport coordinate.
      o n%                  A value indicating which coordinate is returned:
                            startcoordinate#        n%   Returns
                            ---------------------   --   ---------------------
                            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

DESCRIPTION
  Returns the window coordinate equivalent to a viewport coordinate, as defined
  by the WINDOW statement, or vice versa.

  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)
