  18. Thanks.  I think you're right, Mark.  For this sort of thing, a series of
  19. if-then statements is probably more straightforward than the case
  20. selection expression.  But it's good to know alternative ways of skinning
  21. the proverbial cat.
  22.  
  23. By the way, what is the story with "<-"?  Is it just a variant of ":="?
