How do you write to external .txt files so that you can read from them like this;
on (release) {
    loadText = new loadVars();
    loadText.load("hiscore.txt");
    loadText.onLoad = function(success) {
        if (success) {
            // trace(success);
            scoreBox.html = true;
            scoreBox.htmlText = this.hiScore;
        }
    };
}
then there would be a text file called hiscore.txt and it would have
hiScore; 28000
for example
