Finding the Stack that Started Up a Stack

[David Burgun]

Hi,

A quick question, If I have two stacks StackA and StackB:

A script in this StackA executes:

go to stack "StackB"

In StackB (in one of the preOpen or open handlers) is there any way 
of finding out that StackB was run by StackA? I would like to know 
the current Stack that caused StackB to get control?

Thanks a lot
All the Best
Dave
