I need to check to see if the :5.10 is actually necessary for the code as it stands now. Don't particularly like breaking things, but since I've moved on, my code may well have moved on with me. As for 'a gazillion syntax errors' could you provide a screen capture so I can see what you are talking about?
Update: Nice to know there are no syntax errors :) It's always possible that something crept in, but this is version 26 so I'd be a little surprised. Now on the 5.10 front, the total difference was in the use of given/when in a single sub routine! That being the case it was easy enough to revert to pre-5.10 code. It will need a bit more testing, but I think I can safely say that Chess::PGN::EPD-0.27 should run fine under 5.8 etc.
