SUPER is a standard keyword in OOP. It represents the parent class of the class of the current object. I have fixed the example in the wiki (now at http://gambaswiki.org). Not that example is not complete, it just shows how to use SUPER. But it does not exist in all OOP languages. For example, in C++, you have to name the parent class explicitely.
