Terry, Thank you for responding. I actually figured out how to do this shortly after posting the message. Sorry I wasn't quite clear enough in my post, I will try to be a little more explict in the future. Just to mention it I want to go to each node in the ast including child nodes and change the values. I am making a limited mutation analysis program. If it looks generally useful as I get further along I will release the code. I did an early prototype that worked on the text of the code itself but I thought that using the ast for this would be better and maybe a little faster.
