(...) Yeah, very true. Those lines where in there becuase of the error I originally had in my code, but since my code changed (and is correct) those lines are not needed). Thanks Mike (22 years ago, 6-Dec-03, to lugnet.robotics.rcx.legos)

The main problem is of course memory. Under standard firmware, with 32 variables, you're not going to be able to do an A* on much of a grid - 7x7 is about the max, and even then you'd have to fiddle around and store two cells values in a single (...) (22 years ago, 4-Dec-03, to lugnet.robotics)
