This is fairly cludgy code, liable to change on my whim (since currently no-one else uses it), and more importantly, only available if ATC is enabled. It is run by calling 'conventional' class functions, not by setting property tree values. > That way one could easily use Nasal to display runtime info, > one could also use such a feature to indicate things like that > the game's been paused (which is currently not being displayed) Norman did use exactly this (the atc display) to display a 'sim is paused' message once IIRC, but that got removed I think. I guess if you wanted something to get you going for now you could easily write a command binding to the ATC display and hence use it with Nasal, but I wouldn't rely on it in the long term. I was considering displaying ATC messages in pui dialogs, but am not sure if they can be kept on-top persistantly without blocking user input to the rest of FlightGear. The current code can be very hard to read depending on the colour of the background, although I suppose an arbitrary background colour could be drawn behind the text.
