well i havent really seen anyone work with strings and someone already used the idea i was gonna use fireworks =( but o’well what it does is encodes and string
and can decode i think the correct term is encrypt but i used encode well here we go

	_root.createEmptyMovieClip("holder", getNextHighestDepth(), {_x:252.9, _y:147.7}), _root.holder.createTextField("change", getNextHighestDepth(), 252.9, 147.7, 127, 22.1), holder.change.multiline=true, holder.change.html=true, holder.change.htmlText="<u>Change decode or encode</u>";
