Internal high scores (without PHP/SQL/XML), how to?

All I found was the following file:

But when I try to ctrl-enter it from Flash 8, the program hangs and the swf just won’t open…

I’m aware of the fact it’d be much handier via PHP and a MySQL database, but I’m making a game for a contest in which it isn’t allowed to use any additional files (also no txt files) next to the main game swf :frowning: Hopefully someone can help me out!
