Good day monks. I have a socket application running that returns a data structure using a Data::Dumper string. Here is the sub that calls it:
sub processtext {
    my ($hostid,$port,$text) = @_;
    my $socket = IO::Socket::INET->new(PeerAddr => $hostid,
                                PeerPort => $port,
                                Proto    => "tcp",
                                Type     => SOCK_STREAM)
    or die "Couldn't connect: $!\n";
    print $socket "$text\n";
    # read the remote answer,
    my ($blob,$answer,$obj);
    while ($answer = <$socket>) {
        $blob .= $answer;
    }
    close($socket);
    $obj = eval($blob);
    return $obj;
}

At the end of this sub, $obj is an undefined scalar rather than a hash like it should be. The socket app is working and is returning a valid dumper string. I know this because I cut and pasted the value of $blob from the debugger into a separate script and I was able to eval it and get the correct object back.

What could be keeping the $blob string from evaluating properly in this sub? I'm kinda baffled here.

TIA....Steve
