Kevin,

A hook is an empty routine (method or function) which can be overruled (with code in it) in a class or subprogram.

For example if you make a basic formclass you might provide a BEFORESAVE method, which is called in the SAVERECORD method of your class. At default there is no code in it.

But when you create a form based on this class or subclass it, you might want to add some code to the BEFORESAVE method. Such an empty method is called a HOOK. It's not difficult to see the paralells between events and hooks.
