How can I export and import a score in flash?

I run a "Classic Game Show" night at a bar, and have created scoreboards in flash for games like the Family Feud, Wheel of Fortune, and others. Each team gets to compete in a few different games. This is all computer based, not on the web (so no PHP assistance please).

All I want to know is how to export a total score to a .txt or sharedobject file, (I'll set it up so when a keycode is entered, it exports the score value), and then when I switch games, I can import that score value back without having to type it myself on the scoreboard

Please help!
