[REBOL] help from Dixon or others about port

From: rotenca:telvia:it at: 6-Sep-2001 18:16

I've found in rem42.r this line of code: l: open tcp://: out: open join tcp://localhost: l/port-id wait l in: first l I do not understand the last command: in: first l and why does it make a wait before? The command "first port" doesn't give the data in input? Why here does it give a pointer to port? --- Ciao (my english is bad) Romano
