Application in the Mapper programme is a separate module and you can run it anytime.
To load an application it has to be stored in ...\Mapper\Applications folder and you have to enter AL=name command in the command field.
AL means ApplicationLoad, name is an application's name without extension. E.g.: AL=SHOWERROR loads the ShowError application.
Using other functions does not close applications once they are loaded and to unload it use AU=name (ApplicationUnload) command. If an application makes additional functions available you can run them using the AF command. E.g. AF=TRIANGULATION,PROCESS runs triangulation.
