Anyway, I now understand that for a GUI application, which uses forms, I can find the Lazarus version last used by looking inside one of the lfm files last changed. But for the console programs this is not needed and then I could probably just open it in any recent Lazarus since it is just the fpc that is involved here. Lazarus just used as a manager for fpc and as an intelligent editor, right? The current case is this helper console application, but I also have a number of GUI applications that might need work going forward and now I know how to handle these.
