I'm using BricxCC and whenever I've changed something (even a single number) I've to download my program to my NXT. It's a bit slow. But I can live with that. The worst thing is that the connection drops during or after the download quite often (...) (16 years ago, 11-Jul-08, to lugnet.robotics)

| | NXT-G print to text?

In Robolab, one could print to file and read the program methods in text. Is there an equivalent in NXT-G? One of my students has this enormous NXT-G program that is hanging up every workstation we try to debug it in. It has about a dozen loops and (...) (16 years ago, 10-Jul-08, to lugnet.robotics.nxt)

Hi all, Just wanted to follow up on this!
