For-loop-like construction

[GaryCXJk]

Really easy question, but I'm really stuck, or rather, my Wii gets stuck, or, freezes, or crashes or something.

Basically I would like to make a for-loop. Or something similar to a for-loop. I have the amount of times to loop in an adress, say, 81000000, and I, for example, want to get the sum of some consecutive bytes, stored in a random adress, say, 81100000.

Of course, these aren't real addresses, but I just wanted to know, how do I do this? I already tried to understand the repeat codetype, but so far no luck.

isn't there a code that jumps back XX lines for YY times?

You could use an If codetype, then the repeat codetype.
