Close Threads

[candle]

Hey Folks.

I have a question about threading and how to close threads i 
don't need anymore.

In the following code, i build 3 threads with spawn from the 
concurrency module.

if one thread found the number, all others thread must stop 
search.

but i have a big logical problem in my mind.

i hope someone can help me to find a solution.

Happy Greetings
