I think it works the way you want: if  you put a function in your  
mainstack "GlobalStack" whose script is

function ReportMyName
   return the short name of this stack
end ReportMyName

and then you call it from your substack "StackA" (the script of  
"GlobalStack" will automatically be in the message path) say in a  
button which is scripted

on mouseUp
   put reportMyName()
end mouseUp

You'll get "StackA" in the message box, but if you run that script from  
"GlobalStack", you'll get "GlobableStack", or from another substack  
"StackB", then that name. So within the function, 'this' still refers  
to the calling stack. I think this is what you expected.
