The 'quit' command tells the application running the script to quit when
it's finished what it's doing — ie. running the script. Since you have
another command after the 'quit', that command will be executed before
the application actually does quit.
If you want to stop a script on the spot, use 'error number -128'
instead. If it's running as a non stay-open application, it'll quit then
of it's own accord.

Similarly here you have two 'display dialog' commands after 'continue
quit', so these must be executed before the application can quit.
