Hi Eliot,
Sorry I read, checked (the site backend screen), and replied on my mobile. When I back to my PC and check detail the System>Email you mentioned, I see only
<?php

defined('_JEXEC') or die('Restricted access');
?><?php
Am I suppose to copy the php scripts from Hikashop->Display->Views->Invoice, add some lines to display the product-code, paste it to System->Email; then the original email will be replaced by this one?
BTW, to clarify, for the most basic operation, when an order is confirmed, an email (of the invoice) is sent to the client and the System->Main->Emails->Order.creation.notifications.email.address. What is the official name of this email? "email", "invoice", "order", or what?
