Try breaking it down, work it out one step at a time...

1. Scroll text - write the text on a bitmap (CREATE BITMAP), create an image (GET IMAGE) from it and then a sprite (SPRITE). You can now change the position of the sprite in a loop (SPRITE) to make it scroll across the screen.

2. Now apply the same logic, but make a sprite for each leter in the message. With many sprites, you can change the vertical positioning of each one to create a wave effect

3. Sprites can be scaled (SCALE SPRITE), which will allow you to enlarge the words. I would recommending using OFFSET SPRITE in this scenario, so that when you enlarge, the positioning doesn't go to pot.

this is based on 12 pt type (height = 12 and width = 8)

this is for screen width = 640
you may be able to adapt it for your needs.
