<h4 class="subsection">9.1.8 <code>@env</code>{<var>environment-variable</var>}</h4>
<p><a name="index-env-426"></a>
Use the <code>@env</code> command to indicate environment variables, as used
by many operating systems, including GNU. Do not use it for
metasyntactic variables; use <code>@var</code> instead (see the previous
section).
<p><code>@env</code> is equivalent to <code>@code</code> in its effects.
For example:
<pre class="example"> The @env{PATH} environment variable ...
</pre>
<p class="noindent">produces
<blockquote>
The <samp><span class="env">PATH</span></samp> environment variable <small class="dots">...</small>
</blockquote>
