Very useful! I needed to know whether a vi was running in the development environment or from a compiled exe as the application path varies accordingly, with an extra 'layer' being added when the vi is running from a compiled exe.
For example, if you're trying to get the application path for app.exe containing app.vi, under the development environment, it is \path_to_app\app.vi while under the runtime environment, it is \path_to_app\app.exe\app.vi
