The answer again lies in understanding the Functional programming perspective. each function is an expression, each expression is evaluated, each evaluation is a value ! function --> expression --> value. So given a pattern match, the evaluated part of the function is in effect the return value. Does that help ? thanks Saifi. ------------------------------------ http://twincling.org/ http://twitter.com/twincling ---------------------------------------- Yahoo!
