      Notes: Words are tagged by putting a special symbol at
      their front, like #cat, #dog, ... Multiple groups of tagged
      words may be handled by using different tags:
      #cat, $fish, #dog, $bird. Each group may then be accessed
      independently. The tagged words may be names of variables.
      In that case the /REMOVE keyword can be used to remove the
      tags from the string after finding the list of tagged words.
