zencart version 1.3.8a

A question about Zone rates shipping module:
During check out process: step 1 of 3
by default it says: Shipping to NO .. NO is just an example. its the ISO CODE2 for Norway

Is it possible to make it call the 'title' for the iso code .. in this example Norway instead of NO?!

I believe its done in: /includes/modules/shipping/zones.php that needs some tinkering. But i cant figure it out.

any help will be greatly appreciated
