Hi All: Is there a system call to pause a program's execution for a few miliseconds. Something like sleep(500), or wait(500) to make app suspend execution for 500 ms? I'm using CBuilder 5 Pro. Thanks. Warren Stewart

Strange question. How about Sleep(500):
The Sleep function suspends the execution of the current thread for a
specified interval.
VOID Sleep(
DWORD dwMilliseconds // sleep time in milliseconds
);

If you mean precisely 500 ms, as in you want something to happen exactly every 1/2 second, then the answer is 'no'. If you mean at *least* 500 ms, then the answer is: Sleep( 500 ); The reason is that b/c the Win32 family of operating systems are all pre-emptive, non-realtime OS's, the best guarantee they can offer is that your thread will not get the processor for at least the amount of time you tell the OS you want your thread to be out of the queue. -- -- Early Ehlinger CEO, ResPower Inc - Toll-Free : 866-737-7697 -- - RenderFarm - Lightwave , 3dSMax , Bryce , Maya , AfterEffects - --- www.respower.com -- 500+ GHz Starting At USD$0.50/GHz*Hour -- ----------------- SuperComputing For the Masses! ---------------- "I'm so busy programming my computer to let me be lazy, I never get any rest!" - John Kaster

Thanks to all. I didn't find "Sleep" in online help. So wasn't sure if that was the right function.

Sleep() is indeed documented in the online help. However, in Microsoft's help files, not Borland's, as it is a Win32 API function, not a Borland function.
