I tried to email this but AOL appears to be blocking me.
Thanks for your offer of help. I've got the 2.5 SDK installed, and I'll
download BricxCC as soon as Sourceforge comes back up.
The .lsc file is for a robot I've built from the Syngress book "10 Cool
Lego Mindstorms RIS 2.0 Projects". I've attached it, so hopefully you
can tell me how to modify it so I can get it to work.

| (...) I sent you an email with a revised program. To summarize here: 1. comment out the #include <RCX2Def.h> line 2. comment out the rcx_ClearTimers line Hope this helps. John Hansen (21 years ago, 2-Oct-03, to lugnet.robotics)
