I'm not really sure what you're suggesting. I'm using IO::Socket to create the socket. Now I want to draw data from it by calling a function. Here is how it's created: 

        $sock = new IO::Socket::INET(
                   LocalHost => $myip,
                   LocalPort => $port,
                   Proto     => 'tcp',
                   Listen    => SOMAXCONN,
                   Reuse     => 1);
        $sock or die "no socket :$!";
        STDOUT->autoflush(1);
        #main loop begin
        {
        while (($new_sock, $c_addr) = $sock->accept()) {
                ($client_port, $c_ip) = sockaddr_in($c_addr);
                $client_ipnum = inet_ntoa($c_ip);
                $client_host = gethostbyaddr($c_ip, AF_INET);
                next if $kid = fork;
                die "fork: $!" unless defined $kid;
                close $sock;
                if (&readfromsocket(*new_sock)){

In the subroutine I could do this: 
 
      if (defined($lineread = <$new_sock>)) {whatever}

But I want to be able to use another var name in the subroutine.
