Hi, Moses
Sure, can you send me the "working" socket example?

I was talking about the examples in the chap 16 of the book, "Practical
Programming in Tcl and Tk".
e.g.
client example:
set sock [socket -async host port]
fileevent $sock w {set connected l] /*the fileevent will be notified
when the connection occurred */
global connected
vwait connected
/* the above example shows that there are some communications between
the socket and the fileevent */
server example:
set mainSocket [socket -server Accept 2540]
proc Accept {newSock addr port} }
puts "Accepted $newSock from $addr port $port"
}
vwait forever
/* the above example shows that there are some communication between the
server socket and the Accept(callback) functions. */
thanks
david
