No new features - just a few fixes and tweaks: * output files now default to current directory rather than next to source * fixed the __SCOUT bug * fixed the RcxCC problem - two part solution: 1) trailing directory delimiters are now optional on -I (...)

Hi all, I'm new to programing so this may seem like a silly question. I'm using two rotation sensors with the program below to eliminate drift caused by different motor speeds.

This is my proposed solution to the problem with the NQC beta and RcxCC. As a quick recap, the problem is that RcxCC uses an exec line which has one quoted argument ending with a backslash: nqc -E"temp.log" -L"temp.lst" -I"C:\NQC\CC\" temp.nqc The (...)
