I've been re-reading the Scout SDK and came across the following: "Program Block Library (subroutines) The Scout has an extensive subroutine library of general-purpose functions that can help reduce the size of downloaded user programs.

(...) Looking at the Scout SDK, I think it does support the same sleep time command as the RCX - although perhaps not from within a program. There are two things to try: nqc -sleep 0 or add the following function to your program and call it (with (...) (24 years ago, 30-Sep-00, to lugnet.robotics.rcx.nqc, lugnet.robotics.scout)

There is now a .pdf version (which maintains the tables) available at (URL) I tried ps2ascii, but it didn't seem to work. pstotext does work, but the many (very nice) tables get lost. If it weren't for that, I would have converted it all to sgml/xml (...) (24 years ago, 30-Sep-00, to lugnet.robotics.rcx.legos)

Dave, I tried ps2ascii, but it didn't seem to work. The only thing I can suggest is to download a copy of GhostScript / GhostView. If you're using a common Linux distro you've probably already got it - if you're using Windoze, it's really easy to (...) (24 years ago, 30-Sep-00, to lugnet.robotics.rcx.legos)

I've just finished a very cool Camera mount that can be controlled via the web. (Linux, NQC & PHP) I've decided to use my scout because it's so limited.
