First, create a Collection and add a dummy element to it: Set C = New Collection C.Add Null Then, add elements to your stack like this: C.Add E, , 1 To see what's on the top of the stack: C(1) To remove the item on the top of the stack: C.Remove 1

The reason is twofold: readability and performance. When implemented this way, the code is much simpler to read. If you implement a stack the other way around, you will find that although adding elements is slightly faster, due to the implementation of the Collection class removing them takes a lot longer, on the order of the number of elements on the stack.
