Thanks.  But, I see I didn't formulate my problem statement well.  I was 
(naively) assuming there wouldn't be a built-in codec for rot-13.  Let's 
assume there isn't; I was trying to find a case where you had to treat 
the data as integers in one place and text in another.  How would you do 
that?
