This code(below) using two threads, main() and square() which communicates by sending values.

main() generate a series of unique numbers(printed), and square() prints the squared of each serie it gets from.

Am trying to get the same effect , using :

 receive (
    (int num)(...),
  );

Instead of receiveOnly (Tid)(int)

But i get stuck communicating back to main.

Code:
    /*Assuming modules included */

   void main(){
      auto tid = spawn(& square);
      //Series
      foreach(i, 0..100){
        stdout.writef("No %d \t ", i);
        tid.send(thisTid,i);
     enforce(receiveOnly!(Tid)== tid);
      }
 }

//Now the sqaure
void square(){
    for(;;){
       auto msg = receiveOnly (Tid,int)();

   stdout.writef("square is %d\n", msg[1]^^2);
     msg[0].send(thisTid);
     }

}

These kind of questions should go to the Learn section of the forum.
Also, what you are trying to accomplish is not exactly clear and the example code that you give doesn't compile without modifications.

One possible cause of your error is the fact that you send a tuple (tid + int) not a single int.

I tried to give a fixed version of your code that used receive(...) here:

You should also signal to the other process that it should stop looping and exit, otherwise an exception get thrown.
