I'm sorry, but I can't quite see what you're talking about. Can you point to existing code where there is such embedded "conf files or source files" so we can better judge the potential benefit? [ And in my experience "not have to worry about it" is an illusion: you can never truly escape the need for escaping. ] > I understand. I see some benefits with no cons. If you don't see the cons, then indeed the tradeoff is clear ;-) Stefan
