You pass state as a parameter in the recurring call. Example loop that receives NN message and returns it as a list: 

  Loop (N) - & gt; Loop (n, 0, []) loop (n, count, message) when calculation & lt; N - & gt; Receive messages - & gt; Loop (n, count + 1, [message | message]) end; Loop (_, _, Message) List: Reverse (MGS)
