Wees dus voorzichtig als je dit gebruikt. Als je geen bestandsnummer ingeeft, dan neemt de functie bestandsnummer 0.

close <span class="nu0">1</span></pre>
<p>
Telkens als je dit programma uitvoert, dan open je Foo.txt, maak je het leeg en zet je er telkens dezelfde inhoud in.
</p>
<p>
Dit is de inhoud van Foo.txt
</p>
<pre class="code">Hello Dit komt op dezelfde lijn na Hello</pre>
<p>
Probeer nu eens de code verschillende keer na elkaar uit te voeren, maar neem de 'Reset 1' opdracht weg. Wat zie je?<sup><a href="nl_reset.html#fn__1" id="fnt__1" class="fn_top">1)</a></sup>
