问： How can I program a waiting function (Sleep) in WinCC?
　　答： The following sample program shows how the "Sleep" is used.
　　#pragma code("Kernel32.dll")
　　void Sleep(int milliseconds);
　　#pragma code()
　　Sleep(1000); //time specification in milliseconds
　　Warning:
　　If you use Sleep(), processing the C s cript is interrupted for the time indicated. Requests for the interrupted function cannot be processed during this time.
