<p>e statement —
This statement may be used to mark the end of the last section of the score.

<h2>Description</h2>
<p>
This statement may be used to mark the end of the last section of the score.

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>e</strong></span> [time]</pre>
</div>
<div class="refsect1" title="Performance">
<a id="idp76551552"></a>
<h2>Performance</h2>
<p>
The first p-field <span class="emphasis"><em>time</em></span> is optional and if present determines the end time (length in beats) of the final section of the score. This time must be after the end of the last event otherwise it will have no effect. "Always on" instruments will end at the given time. Extending the section in this way is useful to avoid prematurely cutting off reverb tails or other effects.
</p>
<div class="refsect2" title="Special Considerations">
<a id="idp76552680"></a>
<h3>Special Considerations</h3>
<p>
The <span class="emphasis"><em>e statement</em></span> is contextually identical to an <a class="link" href="s.html" title="s Statement"><em class="citetitle">s statement</em></a>. Additionally, the <span class="emphasis"><em>e statement</em></span> terminates all signal generation (including indefinite performance) and closes all input and output files.
</p>
<p>
If an <span class="emphasis"><em>e statement</em></span> occurs before the end of a score, all subsequent score lines will be ignored.
</p>
<p>
The <span class="emphasis"><em>e statement</em></span> is optional in a score file yet to be sorted. If a score file has no <span class="emphasis"><em>e statement</em></span>, then Sort processing will supply one.
</p>
