<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.

     <dl>
<dt><code>show language</code><dd><a name="show-language"></a><a name="index-show-language-968"></a>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.

     <br><dt><code>info frame</code><dd><a name="index-info-frame_0040r_007b_002c-show-the-source-language_007d-969"></a>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.

     <br><dt><code>info source</code><dd><a name="index-info-source_0040r_007b_002c-show-the-source-language_007d-970"></a>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. 
</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:

     <dl>
<dt><code>set extension-language </code><var>ext</var> <var>language</var><dd><a name="index-set-extension_002dlanguage-971"></a>Tell <span class="sc">gdb</span> that source files with extension <var>ext</var> are to be
assumed as written in the source language <var>language</var>.

     <br><dt><code>info extensions</code><dd><a name="index-info-extensions-972"></a>List all the filename extensions and the associated languages. 
</dl>
