Hi,

I've searched Dejanews, and looked through "Common Lisp", and I can't find
an answer to this question.

Does anyone know how to create a non-printing ASCII character?  
Specifically, I have a socket connection to a program in another
language.  To tell this program that I'm done sending characters, it
expects a NULL character (in C, it would be "\0").  How do I specify that
that is the character I want?  Thanks very much.

- Bob

Oops.  According to time-honored tradition, the moment I assured that I
would look like an idiot, I found the answer.  There is a function 
(char-code n), where n is the code, and it returns the character.  I
swear, this wasn't in the book yesterday...

That should be (code-char n).
