<div>Dear all,</div>
<div><br>
</div>
<div>out of curiosity I made a small animation ... see code
below.</div>
<div><br>
</div>
<div>Note:<br>
</div>
<div>The part of the sound section is from a example where I
generate different tones within one sound file.</div>
<div>Hence the intervalls....</div>
<div><br>
</div>
<div> </div>
<div>To the topic:</div>
<div><br>
</div>
<div>The animation runs in a while loop.</div>
<div>It is possible to stop the loop, by just closing the figure
that displays the animation.</div>
<div>However this is kind of crashing the program.</div>
<div><br>
</div>
<div>Question: <br>
</div>
<div>Is it possible to have a function within the loop to check
if a specific key is pressed?</div>
<div>And if this key is pressed, the control variable of the
loop changes and the loop stops? <br>
</div>
<div><br>
</div>
<div>Thank you,</div>
<div>Philipp</div>

<div>Here the code (Scilab 6.0.2)</div>
