DoEvents: Getting other events to process during a loop

DoEvents: Getting other events to process during a loop

DoEvents: Getting other events to process during a loop

(OP)
I have a simple while loop:
____________________________
while play
            wavplay(wavout,Fs)
end
____________________________

The problem is that it is supposed to stop when the user presses the stop button, which will make play = 0, stopping the loop. But during the loop, the user can't press anything. I need something equivalent to the DoEvents in Visual Basic, that will let other events process.Thanks.
