Luca,
this is precisely why I asked!
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.

Thanks all!
