a little tutorial STEP by STEP on scrolling in 2D graphic mode
#5
I've got a boatload of programs with the background image being bigger than the visible screen, and which scroll up/down.  It's a common technique which I use for quickly and easily making a scrollable screen with more information than what you can normally find on a single page.

Make a background image 32000 pixels tall, print/draw all you want on it, and then display your _Height from StartY to StartY + _Height to put the portion of the image on the screen that you want.

Bonus points involved if you include a slider on the side which you can use for navigation as well.  Wink
