<dl class="function">
<dt>
<a name = "create"></a>
<strong>create ()</strong>

<pre class="example">f = create(); f:write(<span class="string">'hello, dolly\n'</span>); <span class="global">print</span>(f:value())</pre>
</ul>
</dd>
<dt>
<a name = "open"></a>
<strong>open (s)</strong>
</dt>
<dd>
create a file-like object for reading from a given string.
<h3>Parameters:</h3>
