You can cycle through the list just like you would with any array. The easiest approach is likely a foreach loop:

use strict; 
use warnings;

use constant VALUES => qw(1 2 3 4 5);

foreach (VALUES) {
    print;
}

As a side note, in your OP you have used a comma-delimited list with qw delimiters - see the information on Quote and Quote like Operators in perlop. If you are not getting the results you expect, I'd bet that's your issue and use warnings; will tell you as much.

Lastly, since you are trying to use <br> tags, you should read Markup in the Monastery.
