Sent to the current card when the stack closes.Syntax:



on closeStack -- automatically save changes
  save this stack
  pass closeStack
end closeStack

Handle the closeStack message if you want to perform cleanup or do other tasks when the user closes a window.

A stack is closed when the user or a handler closes the stack window.

The actual closing is not triggered by the closeStack message, so trapping the message and not allowing it to pass does not prevent the stack from closing. To prevent a stack from closing, trap the closeStackRequest message.
