Alright, but I guess what I am missing is HOW do we handle the 
excpetion? I see now recuse statement.

Maybe I am missing something obvious but, with Java the method signature 
indicated the exception being thrown. That way in the calling method I 
could deal with it. In this example while I understand that the file 
handle will be closed how do you handle an exception raised?

Thanks for your help!
