Is there any way to "re-declare" an array? For example, doing "Data(0,0,0)->GDB0" at one point, then doing "Data(6,3,5)->GDB0" later? Or, after the array has been declared, would I need to do something like "6->{GDB0+0}:3->{GDB0+1}:5->{GDB0+2}" to change values?

If your program doesn't writeback, then this is okay. It would be much easier to store values to a free RAM space, then alter them there.

How would I learn tilemapping/scrolling for a platformer? I don't know how to adapt the ones in the tutorials section to make it work.

I found it difficult to follow Yunhua's tutorial
I learned it from aeTIos and butts.
But, I'll show you how it works.

Alternatively, you can store data to a variable instead of a constant and then your can re-assign pointers all you want.

Ahh, thanks guys!

What does ? do?

I am prety sure it is the same.
but can be used for other optimizations because it works inline.

getKey(2)?X--

Evidently not, when I tried something like that it threw an error at compile-time.

i think that is becasue X-- is a command, not a value.  Try x-1->x
