 | | NQC 1.0 compatibility mode
|
| Would anyone miss terribly the NQC 1.x compatibility mode if I were to remove it? At this point it seems like it is a very useless feature, but maybe someone out there is still using the 1.x API. What do you think? John Hansen (20 years ago, 6-Jan-05, to lugnet.robotics.rcx.nqc)

I don't want to go through the long route which is to save the light values from different sensors to different container, then, compare them. How about using "formula (...)
