Everyone, Being fair in the judgement in using a global watchdog flag to terminate a task. Honestly, when I have a multi-threaded process, I have always used a watchdog type of flag, mutex, semaphore, etc. to signal a thread to terminate. I hardly (...)

(...) Well, you may not consider that awkward, but having been able to use the "stop" & "start" task commands in NQC, I do actually consider it very awkward. For instance, if I want to immediately stop some task under the "stock" FW... well, I (...) (17 years ago, 24-Jul-07, to lugnet.robotics.nxt)

(...) It is not a rather awkward option, imho. That's like saying breaking out of an infinite loop using a flag is awkward and that it would be better to have some form of stop loop keyword that you could use from outside the loop instead.

(...) Using a global to flag out of a task is about the only (rather awkward) option I know of. This is one of the things that I really have issues with under the NXT-G FW. (17 years ago, 24-Jul-07, to lugnet.robotics.nxt)

I just noticed that there is no function to terminate a task like nqc . "stop" . I am currently setting up a global watchdog variable to signal a task to exit. Suggestion? --Elizabeth (17 years ago, 24-Jul-07, to lugnet.robotics.nxt)
