Dear Monks, In furthering my explorations into text mining and comparison, I'm looking to try and take two strings from a database (which represent sentences), split them into pieces if they are unequal. What I want to do is to compare $additional against $index and then print out the differences between the two which I'll ultimately write to a file though at the moment, I'd be happy to only print out the diffs. 
#!c:\perl\bin\perl.exe

use strict;
use warnings;

use DBI;

my $index;
my $additional;


#Create the strings first
my $db = DBI->connect('dbi:mysql:sequence:localhost', 'db', 'pass');
my $sth = $db->prepare('SELECT * FROM milton');
$sth->execute();
my $indexstring = $sth->fetchrow_array;

$sth = $db->prepare('SELECT * FROM milton1');
$sth->execute();
my $additionaltext = $sth->fetchrow_array;

print "$indexstring\n";
print "$additionaltext\n";

if ($indexstring eq $additionaltext) {
  print "lines match";
  }
else {
print "lines do not match";
#$index = split //, $indexstring;
#$additional = split //, $additionaltext;
}

$sth->finish;
$db->disconnect();

The error message that I was getting says that use of @_ is deprecated in split but is there a cleaner, more efficient way of achieving my desired result? Thanks.
