My comment:
WinNT4, User32.dll of apr-99: Cannot find entry point BlockInput in the DLL.

During the cycle of N times running the DATAPROC, the user input is practically blocked. You can not even access the Task Manager.

Though the good old CTRL+ALT+DEL still can break through. It is quite helpful in case you have a run-time error within this cycle. Otherwise you could not be able to get out.

Note that no key presses reach the keyboard buffer during the blocking. And this is not the delay like the Sleep function creates.
