As an alternative, you might want to look at the ROBOTC solution. It fully supports two dimensional arrays. You can download a 30-day evaluation version from www.robotc.net. It's best to use the pre-release version (1.22 or higher) if you'll be (...) (17 years ago, 30-Mar-08, to lugnet.robotics.nxt)
