Sleep (int milliseconds)
Windows API function; freezes the program and suspends execution for the given number of milliseconds.
wait (int n): int
Like Sleep, but does not freeze the program. The user interface remains responsive during the wait time,
given by n in milliseconds. The function returns 0 when the [Stop] button was hit, otherwise nonzero.
If n is negative, the function checks the [Stop]
button and the user interface only every nth time, for not
delaying fast loops. Use wait in a loop for avoiding unresponsiveness during long computations or external function calls.
For displaying progress during very long processes, use
Rx("TrainNeuralNet()",1); // start a long computation
while(Rrun() == 2)
if(!wait(100)) return; // wait until computation is finished or [Stop] was hit
