Creating a procedure and function HELP

Hi,

Can anyone tell me what the difference with the keyword 'IS' and 'AS' when used after the declaration of the procedure of function.

Example:

CREATE OR REPLACE FUNCTION(val VARCHAR) RETURN VARCHAR2 IS

CREATE OR REPLACE FUNCTION(val VARCHAR) RETURN VARCHAR2 AS

When do you use 'IS' and when do you use 'AS'????
