Description 
INDEX Top; 
This is the index of the next pointer to be pushed or popped. If top == 0, the stack is empty, until a pointer is added and top is incremented. 
INDEX Cnt; 
How many pointers the stack can contain. 
_32 Lock; 
thread interlock using InterlockedExchange semaphore. For thread safety. 
_32 Max; 
a defined maximum capacity of stacked values... values beyond this are lost from the bottom 
POINTER pNode[1]; 
Reserved data portion that stores the pointers. 
Description

This is a stack that contains pointers to user objects.

Remarks

This is a stack 'by reference'. When extended, the stack will occupy different memory, care must be taken to not duplicate pointers to this stack.
