Aaargh, ok, so sorry to disturb (but i will be happier if TApplication
was part of FCL). ;-)
No, because TApplication needs references to GUI related things (e.g. on
Windows a reference to a hidden application window). The FCL is not
about GUI, so TApplication has no place there. For programs that don't
need a GUI you can take a look at TCustomApplication in unit CustApp
however (which TApplication also inherits from).
