How to make display move left and right

[Art]

You haven't provided a picbasic source file.
A hex file is of no use to anyone trying to help you.

but in short, start printing from an offset to the data you are printing (to move it left and right).

ie. the data (hello world) starts at offset of zero "h".
print from offset 1 ("ello world") and you just moved one step right (display moved left).
Same if you are dealing with graphics.
