That last comment actually helped, thanks! I converted it into 2 single dimension arrays and it now works for that set. Larger arrays seem to crash it now (clicking), but I will try splitting them into smaller chunks and using OpenFileAppend().spillerrec wrote:I think you are running into some bug totally unrelated to file IO. The program suddenly misbehaves, crashes, or even freezes the NXT when small changes are introduced. So I suspect it is some kind of firmware or compiler issue, perhaps because of the large array. (The complier creates 545 temporary arrays in order to build it.)
