OK,

then I have a problem: I want a piece of code be a part of different prgs.

Actually I have several projects, whoes main programs differ only slightly. 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. Only the end of the main prg is specifical to the app. itself.

I would of course like to maintain this common part separately in a prg-file. But then I have to somehow "#INSERT" it into the code at compile-time, otherwise I can't declare the variables in it.

You are right, I did such thing before in FP26 with menus...
