Hi,

           Just kind of curious what people think.  In your opinion,

should a function avoid output? What I mean by that, is should a function on "do something" without having echo or printf commands in it? This is something I've been thinking about lately to improve my programming style. Opinions? -Dan Joseph Most functions I use don't output anything, but there's always going to be a case where a rule must be broken.
