  Usage:    <integer> = enhanced([<color>])
  Params:   integer <color> - new enhanced color to use by get/read
  Returns:  integer equal to the current enhanced color setting

 ---------------------------------- Example ---------------------------------

                 ? enhanced()
                 print(10,0,"enhanced  color",enhanced())

                 enhanced(23)
                 * sets screen gets to white on blue

  Note:     The enhanced color is the color used for the GET. Useful
            for writing generic menu routines that work off the
            set color to settings. The integer returned is
            compatible with the FUNCky color notation of
            ((background*16)+foreground)
