EXAMPLE 2
MAXIMUM STACK DEPTH
According to this old blog the maximum stack depth is 30. When the stack is full, any new value pushed onto the top causes the bottom value to be removed and discarded.
CLEARING THE STACK
The stack is cleared at the beginning of each gauge cycle, or by applying the Clear Stack XML operator, "c". Of course, also during a panel Load/Reload.
DIFFERENT STACKS
The stack is shared between <Update> and all of the <Element> set. As well, each <Area>, <On Event> and <On Key> structures hold their own stacks.
STACK GAUGE
Attached to this FSDeveloper thread is a simple XML gauge that can be used to view the stack at any point in an XML script. To understand what the lesser known XML Operators actually do or to Q/C complicated script logic, it is sometimes useful to see the stack, step by step.
