Thanks Andy.
I guess I wasn't clear, I do have the data sheet, but have not found how to do this. If it is in there, it's not very clear (at least to me)

I have tried several different scrolling methods, some of which were in links that I found by searching the PBP forums.
Yes, they all do a nice scroll, but on a 4 x 20 LCD screen the text "wraps" from line one to line 3 , and after line three scrolls off, it "wraps back to line one. I only want to display the scroll on Line one.
