TV_number_info (ul_oocbs)


   This module defines a "button" object for use with the TV window
   interface. A TV_number (a "changeable" TV_button) inherits all of
   the functionality of the TV_button class, with the additional
   functionality of being able to change its appearance (text, or label)
   by reading from the "TV" screen.
