the CatWalk example of thread control was written by Ron Thomas long times ago. it was a better example about thread control.
i translated it into x64 Uasm style. and added these "ExitThread,Ret "s function for a thread Exit.
pay attention to:
1. can't use ExitThread in your main thread, Use only own threads which will be exited.
2. monitoring the number of execution threads. 
3. relate to I/O, DLL, MEMORY. "RET" is best. "ExitThread" is better. "TerminateThread" isn't good on unless necessary

The SetThreadPriority parameters are a bit old.https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-setthreadpriority
I have changed those old parameters by the new in the upper link.
I have also added some various error messages.
bad parameters could be :

This value can be specified only if hThread is a handle to the current thread. The function fails
take care of that

hi,TouEnMasm
thank for you'd done on updating. :thumbsup:
There are more functions of thread control:
1. update to 9 levels priority;
2. add to the errors checking;
;----------------------------------------------
the deeper impression is used to translate between the list index and the priority index.
