So what I want is process A to broadcast a message to say processes B to D. How can this be done? The right way of doing so seems like to have channels between A and processes B to D and then to just send the same message to each of the process from B to D, as follows.
chanA2B ! message
chanA2C ! message
chanA2D ! message
Is this the right way to mimic broadcasting in PROMELA, or is there a proper operator for doing so?
