Location/Initialize Session Variable

[DLLong]

Since I'm coming over from the dark side (Windows/ASP), I could use some help in finding out how ZenCart sets "session variables." Specifically, let's use PRODUCT_NEW_LIST_DESCRIPTION for an example. I see in several places that the code

if (PRODUCT_NEW_LIST_DESCRIPTION != '0') { <take some action>


Where is this variable pulled from the database and how is it initialized?

Thanks in advance.

Those are not session variables.

That is a PHP constant, which is set based on a configuration key by the same name set in the configuration table in the database. Those configuration keys are set via the Admin interface -- most of them under the Admin->Configuration menu choices.

The correct place/way/method to set/change that setting is via the admin UI.
