in reply to Tcp client and servers

Graham Barr didn't seem to understand that errors for "system-related" operations should be returned by setting $! to something sane, and instead put the error text in $@, which is reserved for eval errors. No amount of pleading with him has seemed to convince him that he needs to set the appropriate value.

So try looking in $@ instead of $! when you get an IO::Socket::mumble error.

    Thanks for your reply
    I solved the problem eventually. I had hardcoded the computer name address in the server program and used the hostname() method
    in the client program. Even though both programs sat on the same computer, the client could not figure out where to
    send the data to.
    All this became a little clearer when I put in the -w switch in at the top. But i have now inserted $@ instead of $i in the code.
    many thanks
