The Twelve Days of Christmas is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
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)
