+<h3 class="section">15.2 Displaying the Language</h3>
+
+<p>The following commands help you find out which language is the
+working language, and also what language source files were written in.
+</p>
+<dl compact="compact">
+<dt><code>show language</code></dt>
+<dd><a name="show-language"></a><a name="index-show-language"></a>
+<p>Display the current working language. This is the
+language you can use with commands such as <code>print</code> to
+build and compute expressions that may involve variables in your program.
+</p>
+</dd>
+<dt><code>info frame</code></dt>
+<dd><a name="index-info-frame_002c-show-the-source-language"></a>
+<p>Display the source language for this frame. This language becomes the
+working language if you use an identifier from this frame.
+See <a href="Frame-Info.html#Frame-Info">Information about a Frame</a>, to identify the other
+information listed here.
+</p>
+</dd>
+<dt><code>info source</code></dt>
+<dd><a name="index-info-source_002c-show-the-source-language"></a>
+<p>Display the source language of this source file.
+See <a href="Symbols.html#Symbols">Examining the Symbol Table</a>, to identify the other
+information listed here.
+</p></dd>
+</dl>
+
+<p>In unusual circumstances, you may have source files with extensions
+not in the standard list. You can then set the extension associated
+with a language explicitly:
+</p>
+<dl compact="compact">
+<dt><code>set extension-language <var>ext</var> <var>language</var></code></dt>
+<dd><a name="index-set-extension_002dlanguage"></a>
+<p>Tell <small>GDB</small> that source files with extension <var>ext</var> are to be
+assumed as written in the source language <var>language</var>.
+</p>
+</dd>
+<dt><code>info extensions</code></dt>
+<dd><a name="index-info-extensions"></a>
+<p>List all the filename extensions and the associated languages.
+</p></dd>
+</dl>
