SHWCLHELP.HLB  —  PAN
  The PAN command pans the entire display by column or by line. The PAN
  command functions in a way similar to the panning of a television or
  motion-picture camera. By entering a PAN command, a portion of the
  display that previously extended beyond the limits of the screen can
  be brought into view.  For more information, see help on SET FUNCTION.

  Format:  PAN UP value
           PAN DOWN value
           PAN LEFT value
           PAN RIGHT value

  The display description message at the top of the screen always remains
  stationary. The arrow keys can be redefined as PAN commands.
