st4k, as rchiav stated and as I showed you earlier, you probably don't want to store the newline characters in your array. In my example using print join("\n",@out); I demonstrated a way to manipulate the array (without changing its contents) and printing the results each element on a new line. By storing the data without newlines you could also do something slightly different:

my @out = qw(one two three four five six seven eight nine);
my $i = 0;
foreach (@out) {
   print "\$out[",$i++,"] = '$_'\n";
}
=output=
$out[0] = 'one'
$out[1] = 'two'
$out[2] = 'three'
$out[3] = 'four'
$out[4] = 'five'
$out[5] = 'six'
$out[6] = 'seven'
$out[7] = 'eight'
$out[8] = 'nine'

But if you had stored the newlines in the array, the last ' in each line would've been pushed to the next line by the newline character stored in the array:

=output=
$out[0] = 'one
'
$out[1] = 'two
'
$out[2] = 'three
'
$out[3] = 'four
'
$out[4] = 'five
'
$out[5] = 'six
'
$out[6] = 'seven
'
$out[7] = 'eight
'
$out[8] = 'nine
'

You have more flexibility if you store only the data.

In your example @out = join "\n", @out; you are destroying your array. Instead of the output above you would get the following output using the same print loop:

my @out = qw(one two three four five six seven eight nine);
@out = join "\n", @out;
my $i = 0;
foreach (@out) {
   print "\$out[",$i++,"] = '$_'\n";
}
=output=
$out[0] = 'one
two
three
four
five
six
seven
eight
nine'

Instead of having 9 rows you now have only one row made up of a string with interspersed newlines. As a rule, most people don't print an array using   print @array; except when debugging.

Try playing around with the print loop above to test other types of array manipulation. It will give you a better idea of how your data is stored in the array structure.
