  64. <h3 class="section">15.2 Displaying the Language</h3>
  65. <p>The following commands help you find out which language is the
  66. working language, and also what language source files were written in.
  67. </p>
  68. <dl compact="compact">
  69. <dt><code>show language</code></dt>
  70. <dd><a name="show-language"></a><a name="index-show-language"></a>
  71. <p>Display the current working language. This is the
  72. language you can use with commands such as <code>print</code> to
  73. build and compute expressions that may involve variables in your program.
  74. </p>
  75. </dd>
  76. <dt><code>info frame</code></dt>
  77. <dd><a name="index-info-frame_002c-show-the-source-language"></a>
  78. <p>Display the source language for this frame. This language becomes the
  79. working language if you use an identifier from this frame.
  80. See <a href="Frame-Info.html#Frame-Info">Information about a Frame</a>, to identify the other
  81. information listed here.
  82. </p>
  83. </dd>
  84. <dt><code>info source</code></dt>
  85. <dd><a name="index-info-source_002c-show-the-source-language"></a>
  86. <p>Display the source language of this source file.
  87. See <a href="Symbols.html#Symbols">Examining the Symbol Table</a>, to identify the other
  88. information listed here.
  89. </p></dd>
  90. </dl>
  91. <p>In unusual circumstances, you may have source files with extensions
  92. not in the standard list. You can then set the extension associated
  93. with a language explicitly:
  94. </p>
  95. <dl compact="compact">
  96. <dt><code>set extension-language <var>ext</var> <var>language</var></code></dt>
  97. <dd><a name="index-set-extension_002dlanguage"></a>
  98. <p>Tell <small>GDB</small> that source files with extension <var>ext</var> are to be
  99. assumed as written in the source language <var>language</var>.
  100. </p>
  101. </dd>
  102. <dt><code>info extensions</code></dt>
  103. <dd><a name="index-info-extensions"></a>
  104. <p>List all the filename extensions and the associated languages.
  105. </p></dd>
  106. </dl>
