# Examples

on deleteStack -- warn the user if the mainStack of the owner of the target \ is not the owner of the target then -- it's a substack answer "This stack will be permanently deleted the" && \ "next time you save the file." end if pass deleteStack end deleteStack

# Description

Handle the deleteStack message if you want to perform cleanup before a stack is deleted from its stack file.

The actual deletion is not triggered by the deleteStack message, so trap the message and not allowing it to pass does not prevent the stack from being removed.

If a stack's file is deleted with the delete file command (or by the user), and the stack itself is not open, no deleteStack message is sent.
