These are the default values for the global variables which will be stored in the properties of the scroll variable: 
  MESSAGE  = "Your message"   -- The text you want to scroll.
                                 [Put into scroll.msg]
                                 
  DELAY    = 50               -- The delay (in milliseconds)
                                 between each shift left.
                                 [Put into scroll.delay]

  POSITION = 100              -- How many spaces should lead the 
                                 message when it starts?
                                 [Put into scroll.pos]
