Thanks to Pete Gontier and Dennis Cohen for cleaning up after me; 
NumToString does indeed take a LONGINT and still works with my example 
(which I stole right out of some of my own code) for precisely the reason 
that Dennis says; Pascal sign-extends integers for you if you pass them 
where you should be passing a LONGINT.

Just because I work for Apple Computer, Inc. doesn't mean that I believe 
what they believe, or vice-versa.
