Hi John! I think there is not an urgent need for a clear-screen flag in a bunch of NXT screen functions. That is, my sources are full of "false," flags :-) TextOut(...,true,...); TextOut(...,false,...); TextOut(...,false,...); LineOut(...,false); (...) (19 years ago, 14-Feb-07, to lugnet.robotics.nxt)

The NXT-G firmware implementation for mailbox messaging is extremely funky. I don't think your code is working properly for this implementation. You need to be continuously calling "ReadMessage" and only check for "a message was found" error code. (...) (19 years ago, 14-Feb-07, to lugnet.robotics.nxt)
