10.2 Port Connections

Another way of specifying connections is with port connections. A process instance p, whose type contains N ports can be connected: p(...) with N comma-separated optional references.

     p(x, y, , z, );
     is equivalent to writing:
     p.port1 = x;
     p.port2 = y;
     p.port4 = z;

A port connection must be written with the exact number of slots as ports in the process definition, where references may be omitted.
