Mission Scripting?

[SEE]

I have been looking at some of the missions in the 'Spitfires over Dunkirk' campaign to see how the author has enabled text information to be displayed on the screen as the mission progresses.

1. Does anyone know how this is done?

2. If scripting in C+, is it done in FMB using the Script window that is part of the Action Trigger menu (I cannot find any script commands in that window)?


The campaign also uses a lot of Action - Trigger commands to spawn groups but I always understood that the Action - and related Trigger should have identical names. In this campaign they are different and yet they work, it seems as though the Action and associated Trigger are referenced in an entirely different way.


I would like to use some of these features in my future missions but looking at the missions in FMB does not reveal how the author implemented them.
