Hi,

Thank you all for the replies and useful help. I came up with my demo 
code.

class Array
    def my_sort
        if not block_given?
            return self.sort!
        end

        (0...self.size).each do |i|
            (i+1...self.size).each do |k|
                self[i], self[k] = self[k], self[i] if 
yield(self[i],self[k]) > 0
            end
        end
        self
    end
end

puts( [5,9,6,7,8,1,3,2,4,0].my_sort {|a,b| a <=> b})

Now it makes sense.

Regars, Jorge
