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!

The neighbor was nice enough to give us all of (...) (16 years ago, 9-Jul-08, to lugnet.robotics)
