Hmm. I did mean it that way and it does sound weird but I thought about what I wrote yesterday and said to myself- "Why did I go into that?
A pointer, when used for graphics, is telling the machine which line of graphics it's on. If you have an 8x8 sprite for example, and Atari can only draw one line of the screen, you have to put in a series of eight 1x8 slices of your graphic using the pointer.
