This program provides a good example of adding and deleting items in an array. The code is challenging and if you follow it all you show promise as a programmer. The display of the credit uses the bitmapped font already built into the W3BMPFont unit while the rendering of the scrolling message requires an image of all of the characters (res/fnt16x16.png) as a resource. Note the use of a callback to run the Resize procedure after an interval.
