Basically just to keep it simple.  Saving space is not really a concern in
the early part of the book.  I'll have to look, but I'm also not certain
I've covered the byte-sized instructions yet in the book.  Also, it makes
sense to do it this way since the byte liitation is only because of the
return mechanism - so it should be easy to modify it to work with larger
numbers after learning how UNIX files work.
