Hi Mukund, I don't think the function can return two times 3,9 because you have provided the return type as unit ,"void" in java.So method g() can't return anything ,so it returns unit if I am not wrong. Just try to do do this val x=g() you will notice that x is now of type g. Reason you get 3,9 is that inside that function you've defined another method and that method is called twice and that method "max" also return unit only ,but first it prints 3 then returns unit.Then it prints 9 and then returns unit finally the function "g" returns unit. As far as your first question is considered...I din't understood why it was giving that error . Can somebody throw light on that peculiar behaviour. Thanks, RajkumarGoel

Another query is a "def" or "a method as in java" automatically returns the value..(No need to give explicit return) "The value evaluated recently"..So once it returns a value How can it again evaluate max(3) ???? I mean how can we have two returns. thanks, SMS [Non-text portions of this message have been removed] ------------------------------------ http://twincling.org/ http://twitter.com/twincling ---------------------------------------- Yahoo!
