I think you are following me now. the LCD is really static, not scrolling, the array is what scrolls. Yes, as I posted in the beginning, start with the array filled with blank spaces or " " if you will.
try it out at first with just adding a number to the array every second, then updating the LCD. it should have the scroll effect you are looking for. The number you add to the array should be a random number, I don't recall if PBP has a random number generator, but you could just increment the number for now.
Once you have that worked out, move on to making the aim change as you press the aim button. from there its all just logic and playing with the array.
