about using symbols for `current-state': 

  `current-state' is incremented, so i wonder whether it's better to use
  numeric constants to represent states instead -- he says, w/o checking 
  whether there are constants ;-).  is it possible to have the state 
  transition code be simple (e.g. via incrementing + one reset) and
  use symbols?

about using `case' in place of `cond':

  the code has been rewritten to use `case'.
