<h2>Pragma Scope</h2>
<p> The scope of a pragma setting is usually limited to a single compilation unit.</p>
<p>As discussed in <a href="pragma_syntax.htm">Pragma Syntax</a>, you should use <span class="code">on</span> or <span class="code">off</span> after the name of the pragma to change its setting to the desired condition. All code after that point is compiled with that setting until either:</p>
<ul>
<li>You change the setting with <span class="code">on</span>, <span class="code">off</span>, or (preferred) <span class="code">reset</span></li>
<li>You reach the end of the compilation unit</li>
</ul>
<p>At the beginning of each file, the compiler reverts to the target or default settings.</p>
