I'm trying to make a Jabber bot and I am having trouble keeping it running while waiting for messages. How do I get my script to continuously run? I have tried calling a subroutine that has a while loop that I, in theory, have set up to check for any messages and react accordingly but my script isn't behaving that way.

Here is my source: http://pastebin.com/03Habbvh

# set jabber bot callbacks
$jabberBot->SetMessageCallBacks(chat=>\&chat);
$jabberBot->SetPresenceCallBacks(available=>\&welcome,unavailable=>\&killBot);
$jabberBot->SetCallBacks(receive=>\&prnt,iq=>\&gotIQ);

$jabberBot->PresenceSend(type=>"available");
$jabberBot->Process(1);

sub welcome
{
    print "Welcome!\n";
    $jabberBot->MessageSend(to=>$jbrBoss->GetJID(),subject=>"",body=>"Hello There!",type=>"chat",priority=>10);
    &keepItGoing;
}

sub prnt
{
    print $_[1]."\n";
}

    if($msg->GetType() ne 'get' && $msg->GetType() ne 'set' && $msg->GetType() ne '')
    {
        my $jbrCmd = &trimSpaces($msg->GetBody());
        my $dbQry = $dbh->prepare("SELECT command,acknowledgement FROM commands WHERE message = '".lc($jbrCmd)."'");
        $dbQry->execute();
        if($dbQry->rows() > 0 && $jbrCmd !~ /^insert/si)
        {
