Is there any board where we can discuss about this further? I am pretty interested in Zoom Math

How did the 86 edit programs then?

You cannot read back into GDB1. You have to read it back either from your appvar of copy()ing it to a list.

Hmm, seems that you all have troubles understanding.
So what do the hex numbers in the GDB mean?
Those numbers represent the position of the sprite in pic1 +1
So, if you have 3 sprites, one being +,another an X, and the other an O and they're all stored in a row in pic1, you could get this tilemap: (.. means a blank "tile")

OXXO
+....+
X....X
O++O

This would be represented by this map data:
[03020203]->GDB1
[01000001]
[02000002]
[03010103]

I hope this is more clear.
My point that was not 100% clear to you:
You can store more than one sprite to a pic since a pic is NO MORE than a pointer (which is again just a number)
So have fun storing 15 sprites in a row and play around with it a bit.

Nice! Glad I was clear!

Nice!

^that
I bought. Even thoufh my crappy PC can't run it >.<
