in reply to im bot text responses

sorry for not including more code, i'll put that in now
the code given by wiredcode.com (the one that only has 1 line work, that i cant figure out) was given and is:

-----------------------------------------------------------

Screenname: SCREENNAME;
Password: PASSWORD;
Message;
Hello|Hi|Hey=exact>Hi! How are you?|Hello!;
Are you=>Yep.|Probably.|I dunno.|Nah.;
/Message;
Connect;


-----------------------------------------------------------

now the main perl one that i would want to enter the responses into is called on_im.pl, and it shows and area to enter the responses (if not a command), but i dont know what to put in or how. heres that code

-----------------------------------------------------------
################################
# WIRED BOTS
#
# on_im();
#
# desc: This sub is called when the bot recieves an IM.
# It first grabs AIM default vars.
# Then filters those vars
# Then checks to see if $victim is an idiot
# Then Checks to see if $msg is a command
# If not a command && not an idiot:
# It replies via the custom code (or command sub)
# Then logs the IM
# Then sleeps and sends
#
# recv: AIM's vars w/ $victim, $friend, and $msg as args.
# sends: either a warning, or a message.
################################

sub on_im {


($aim, $evt, $from, $to) = @_;
$args = $evt->args();
($victim, $friend, $msg) = @$args;

#filter $victim, make it lower case and remove spaces
$victim = lc($victim);
$victim =~ s/ //g;

# This Code creates formats $msg the way you (should) want it, without HTML.
$msg =~ s/<(.|\n)+?>//g;


#check against IDIOT LIST
my $idiot = idiots("$victim");


#if an idiot, warn and block him
if ($idiot != 1) {
#otherwise, continue


#check msg vs. list of commands.. call the commands sub
($isacommand,$reply) = commands($victim,$msg);

#if not a command..
if ($isacommand != 1) {
#custom code
#put what you want your bot to do here.
#its better to put it in a sub, so you can edit it later
easily.
#right now its set up to grab a thought from my database
$reply = thought();

#end custom code
}

#LOG this IM..

log_im($victim,$msg,$screenname,$reply);

#SLEEP & SEND!
sleep(dosleep(1,3));
$aim->send_im($victim, "$reply");
#print that the sleep is done..
print " done.\n\n";

}
}

1;

-----------------------------------------------------------
now it also says i could put it in a sub file, so that it would be easier to edit. if i were to, how would i do this?

thanks alot for your help and please respond and email responses to aimbot1@hotmail.com
