Diff return values

I'm not sure if this is the correct place to address the question, if not
perhaps you can point me in right direction.
I'm running the diff command(with no options) within a C shell script on an
HP box. I'm using an awk program to strip off header and trailer records of
files and then comparing them. The return code I get from the 'diff' is a
2. I've looked all over the net to try to find out what a 2 means. The only
thing I can find is that it's an error or it means there is a problem. Can
you help in being more definitive or perhaps point me to where I can get a
better answer. From what I can tell, there is nothing unusual about the
files, either in terms of size or characteristics. They are both ascii text

Thanks.....Pete Arnold
