Subject: Re: Multidimensional hash - get all not blank keys

That was very positive! ;) hehe I agree, it's useful to say positive  
things. It's also useful to not feed people ready-made answers. My  
math teacher always said it's the working that's important, not the  
answer. Of we care about a person's understanding, we'll help them  
learn rather than give them direct answers.
