Topic: Question about Variables

As I've been looking over the coding for FA, I frequently find myself wondering where the variables are coming from. For example:
     

$_POST['qty'] = number_format2($order->line_items[$id]->qty_dispatched, $dec);
        $_POST['price'] = price_format($order->line_items[$id]->price);
        $_POST['Disc'] = percent_format($order->line_items[$id]->discount_percent*100);

In this snippet, where is the 'qty' or 'price' or 'Disc' coming from? Is that a reference to another array or to the database?
If it is a reference to an array, where are the items of that array defined (as in what file)? I am trying to change the line items and it's hard to know what each line item relies on in order to exist.

Thanks in advance for your help!

Re: Question about Variables

Could be default variables injected for Quick Entries or specific instance of certain voucher entry types for invoices.

The stated code appears only once and it is in the function sales_order_item_controls() in the file sales/includes/ui/sales_order_ui.inc.

It is used for Ajax requests for dynamic form population from previously entered values.
