<p><a name="index-Modula_002d2-defaults-850"></a>
If type and range checking are set automatically by <span class="sc">gdb</span>, they
both default to <code>on</code> whenever the working language changes to
Modula-2.  This happens regardless of whether you or <span class="sc">gdb</span>
selected the working language.

   <p>If you allow <span class="sc">gdb</span> to set the language automatically, then entering
code compiled from a file whose name ends with <samp><span class="file">.mod</span></samp> sets the
working language to Modula-2.  See <a href="Automatically.html#Automatically">Having <span class="sc">gdb</span> Infer the Source Language</a>, for further details.
