|Thank you.

Is this what you want?

  class MyClass
    def setab(i)
      @a = i
      @b = i*i
    end

    def reset
      setab(0)
    end

    attr_reader :a
    attr_accessor :b
  end

  ob = MyClass::new()

  ob.setab(5)
  print "a = ", ob.a, "\n"
  print "b = ", ob.b, "\n"

  ob.b = 20
  print "a = ", ob.a, "\n"
  print "b = ", ob.b, "\n"

  ob.reset
  print "a = ", ob.a, "\n"
  print "b = ", ob.b, "\n"

Hope this helps.
