if on the "server" side i have the code :

#!/usr/bin/perl -Tw
    use strict;
    BEGIN { $ENV{PATH} = '/usr/ucb:/bin' }
    use Socket;
    use Carp;
    my $EOL = "\015\012";

    sub logmsg { print "$0 $$: @_ at ", scalar localtime, "\n" }

    my $port = shift || 2345;
    my $proto = getprotobyname('tcp');

    ($port) = $port =~ /^(\d+)$/                        or die "invali
+d port";

    socket(Server, PF_INET, SOCK_STREAM, $proto)    || die "socket: $!
+";
    setsockopt(Server, SOL_SOCKET, SO_REUSEADDR,
                    pack("l", 1))     || die "setsockopt: $!";
    bind(Server, sockaddr_in($port, INADDR_ANY))    || die "bind: $!";
    listen(Server,SOMAXCONN)                 || die "listen: $!";

    logmsg "server started on port $port";

    my $paddr;

    $SIG{CHLD} = \&REAPER;

    for ( ; $paddr = accept(Client,Server); close Client) {
    my($port,$iaddr) = sockaddr_in($paddr);
    my $name = gethostbyaddr($iaddr,AF_INET);

    logmsg "connection from $name [",
        inet_ntoa($iaddr), "]
        at port $port";

    print Client "Hello there, $name, it's now ",
            scalar localtime, $EOL;
    }

and on the "client" side i have :

#!/usr/bin/perl -w
    use strict;
    use Socket;
    my ($remote,$port, $iaddr, $paddr, $proto, $line);

    $remote  = shift || 'localhost';
    $port    = shift || 2345;  # random port
    if ($port =~ /\D/) { $port = getservbyname($port, 'tcp') }
    die "No port" unless $port;
    $iaddr   = inet_aton($remote)         || die "no host: $remote";
    $paddr   = sockaddr_in($port, $iaddr);

    $proto   = getprotobyname('tcp');
    socket(SOCK, PF_INET, SOCK_STREAM, $proto)    || die "socket: $!";
    connect(SOCK, $paddr)    || die "connect: $!";
    while (defined($line = <SOCK>)) {
    print $line;
    }

    close (SOCK)        || die "close: $!";
    exit;

How can i most simplify it so that the "client" will simply send the "server" an array of data (@data) ,and then the server will print this @data and send the "client" $data[1], and the "client" will print it ($data[1]) ?
