Your code did almost that but there was a bug (which I've pointed out).

Not in your code due to that bug but the program that I've shown does 
exactly what you want.

Once one receive() is executed, the program flow continues with further 
expressions. The suggestion that you received was making square() wait a 
second message. It need not be "embedded" at all. All it is needed was a 
second receive() call. That's all... However, that is not what you 
intended anyway.

You wanted stringConverter() to send a message to main(). So, just 
forget about that embeded receive and either do what my program did or 
fix the bug. :) (See my earlier message.)

By having an infinite loop like 'while (!done)'. (Please see my program.)
