(...) Great! I found a Win95 machine and just performed some downloads. All of them completed with no problems. I compiled with NQC 2.0 and 1.x compatibility option. I'm not sure I understand the problems under NT, but at least now I can go on with (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.nqc)

(...) Mario, I just loaded it 6 times in a row without a single error... How? I'm scared but I have to say it... I tried to load the program in Windows 95. There must be something in NT that is preventing to load big programs. I tried to check the (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.nqc)

(...) Thanks for your help. Hope you're wrong, otherwise I have to dramatically downsize my program and make it a lot more stupid :-) Some more info on the problem: - The memory has been cleared before any attempt. - I tried both NQC 1.3 and NQC 2.0 (...)

(...) You're right - I forgot the delay (that's what I get for typing code from memory). Yeah, 'test and set' is the best solution, but unfortunately the RCX doesn't have one. The bitflag stuff is a little ugly for my tastes, which is why NQC does (...) (25 years ago, 2-Oct-99, to lugnet.robotics.rcx.nqc)

Your proposed solution is susceptible to the "lockstep starvation" problem. Lockstep starvation happens when two tasks try to get the lock at the same time and execute the same code in lock step, like so: task 1: lock |= 2; task 2: lock |= 4; task (...)
