The big part of them is the declaration of private variables that are then used in the app, instantiation of some common objects (application, Hauptmenu and so on), and this part is absolutely common to all my projects.

You could make your own "preprocessor", where you search all your PRGs for a certain mark (let's say, "#MYINSERT"), and replace with the contents of the specified file. Then, you would have to compile everything - and do all this in a copy of the project, not in the original. I don't know whether it is worthwhile...

Probably it is better to use parameters to pass appropriate values to a function, or a few public variables.
