It is not the same as an index, and you cannot operate on a POSITION value yourself. GetAt retrieves the CObject pointer associated with a given position.

You must ensure that your POSITION value represents a valid position in the list. If it is invalid, then the Debug version of the Microsoft Foundation Class Library asserts.
