Hi, Normally you can see me in .space, .loc.ca, or org.ca and the like. But now that I have an RCX I want to program a bit. I have written my first NQC program and compiled it using RCXCC. I then downloaded it to my RCX but when I press run the legs (...) (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.nqc)

So does this mean that the RCX acts like a PC in that it does not forget the date/time when it is turned off or the batteries changed? Should I just write a one line program to set the time, and remove the time code from my actual NQC program? Thank (...) (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.nqc)

Instead of sending ByteCodes from the PC and getting the RCX to interpret them, you can construct and send the SetWatch() OpCode plus the correct "constant" time and send it through Spirit.OCX (or directly, depending of the platform). (...) (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.nqc)
