You are encouraged to solve this task according to the task description, using any language you may know.
Write a program that outputs the lyrics of the Christmas carol The Twelve Days of Christmas. The lyrics can be found here.
ActionScript
This program outputs the lyrics to a TextField object. The text field can be scrolled using the mouse wheel (Windows only) or by using the up/down arrow keys on the keyboard.
(Although the code can work in Flash Player 9 by replacing the Vectors with Arrays)
