As we have come to expect, COM uses its own terminology to describe the member functions and associated data of a Dispatch Interface. A member function is formally referred to as a Method, and the associated data is deemed a Property. Therefore, an application can call the Methods of an Object, and read/write the Properties of an Object.
There are three Property procedures available to manipulate an Interface Property: GET, LET and SET. Methods are initiated with a CALL. We'll describe each of these in more depth as we progress through the COM programming section.
