<h3 class="subsection">2.7.7 Metrics and Maintenance</h3>

<p>Certain features of the virtual machine pertain to software development
and maintenance more than to implementing any particular function. The
operations with the mnemonics <code>version</code>, <code>note</code>,
<code>profile</code>, and <code>weight</code> are in this category.
