I'm trying to get input from a file that has three pieces of information in it, a tracking number, a pager number, and the messaging service the pager is programmed on. The data is on separate lines, as in 
tracking number
pager number
paging service

Below is how I'm getting the input. 
$datafile = "CheckUPS.in";
open (DATAFILE, $datafile) or die "Input data not found.\n";
while (<DATAFILE>)
{
    $TRACK = $_;
    chomp ($TRACK);
    $pager = $_;
    chomp ($pager);
    $service = $_;
    chomp ($service);
}

print "$TRACK $pager $service\n";

Here is where I'm generating the output file which a third-party program is going to read as input to generate the message to be sent to the pager. $status is the current status of the package, and $new is the current geographical location of the package when it was last scanned. 
# Generate the outgoing notice, and send it
if (!($old eq $new)) {
    open (FILE,">$WORKDIR/$MAILOUT") || die "Could not open file: $!\n
+";
    print FILE "MSG:\n";
    print FILE "TO:  $pager $service\n";
    print FILE "CONTENTS:  Package ID $TRACK is/was $status to $new\n"
+;
    #print FILE "Status: $status\n";
    #print FILE "Track#: $TRACK\n";
    #print FILE "Old: $old\n";
    #print FILE "New: $new\n";
    print FILE "\n";
    close (FILE);
    if (($PAGER)) {
        $PagerCmd = "echo \"Check UPS Tracking: $TRACK\" | $MAILBIN $P
+AGER";
        system "$PagerCmd";
    }
    #$MailCmd = "cat $WORKDIR/$MAILOUT | $MAILBIN $EMAILS -s \"UPS Pac
+kage Tracking: $status\"";
    #system "$MailCmd";
}

My last output file was 
MSG:
TO:  Airtouch Airtouch
CONTENTS:  Package ID Airtouch is/was   to

The paging service is listed as the recipient and the package ID number. For some reason, the status and location are not making it into the file as well. What should I check in my code?
