(...) Steering under NXT-G is... not exactly intuitive. I tried some experiments a whle back, but I never even tried to play with the steering slider because I had no patience for rough approximations (like trying to see if I had moved the slider (...)

Is there some more detailed (and lower-level) description of how the arrays work in NBC, please? Something that would complement the description in the manual? This is how I see the arrays in NBC/standard firmware: * a compiled program works with (...) (19 years ago, 29-Apr-07, to lugnet.robotics.nxt)

Your results are not at all what I intuitively expect. From your previous posts, I think the "turn ratio" settings you've used range from 0 to +100 in steps of 10. The following table is what I expected. Turn Inner Expected Observed Ratio Wheel (...) (19 years ago, 28-Apr-07, to lugnet.robotics.nxt)

If I write some other file - for example a text file named file.txt, I can write and close, and see it in the list (through findfirst/findnext) successfully. This works both (...)
