I'm trying to use action script to design a piece that has multiple accessibility options(e.g different languages, visually/aurally-impaired friendly etc)

So the template is the same but each mode calls on different variables(txt,img) to give you that mode(eg irish version-whatever)

I'm thinking parent scripts is the way forward- but I'm not an actionscript whizz like you guys.
If there's easier ways or better still- examples I could use, it would mean a lot.
