Re: single letters

Hi, 

How about this: 

(de singleLetter? (item) 
   (if (and (=1 (length item)) (or (low? item) (upp? item))) 
   1 
   NIL)) 

This returns 1 if true then NIL for false. 



But if you just need NIL for false and then the letter itself for true, then 
can be shorten into this: 

(de singleLetter? (item) 
   (and (=1 (length item)) (or (low? item) (upp? item))))
