Thanks for the explanation. It makes more sens, now. I do think it would be a good idea to use at least one more variable to store that information, and avoid overloading $File->{Version}. I do understand that it is not a best practice in terms of perl usage, but keeping in mind that we are heading toward m12n where these variables will be translated to object methods, I think it's important to disambiguate them. cheers, -- olivier
