Subject: hello world (first method)

For the following:

C:\Documents and Settings\nsaunders\Desktop>
C:\Documents and Settings\nsaunders\Desktop>type HelloWorld.rb
#5.times { print "Odelay!" }




def fact(n)
        if n <= 1
                1
        else
                n * fact(n - 1)
        end

        print n

end


C:\Documents and Settings\nsaunders\Desktop>
C:\Documents and Settings\nsaunders\Desktop>HelloWorld.rb

C:\Documents and Settings\nsaunders\Desktop>
C:\Documents and Settings\nsaunders\Desktop>HelloWorld.rb
1C:/Documents and Settings/nsaunders/Desktop/HelloWorld.rb:10:in `*':

        from C:/Documents and Settings/nsaunders/Desktop/HelloWorld.rb:

Does there need to be class defined to call the method?



thanks,
