<h2 class="chapter">15 Using <small>GDB</small> with Different Languages</h2>
<a name="index-languages"></a>

<p>Although programming languages generally have common aspects, they are
rarely expressed in the same manner.  For instance, in ANSI C,
dereferencing a pointer <code>p</code> is accomplished by <code>*p</code>, but in
Modula-2, it is accomplished by <code>p^</code>.  Values can also be
represented (and displayed) differently.  Hex numbers in C appear as
&lsquo;<samp>0x1ae</samp>&rsquo;, while in Modula-2 they appear as &lsquo;<samp>1AEH</samp>&rsquo;.
</p>
<a name="index-working-language"></a>
<p>Language-specific information is built into <small>GDB</small> for some languages,
allowing you to express operations like the above in your program&rsquo;s
native language, and allowing <small>GDB</small> to output values in a manner
consistent with the syntax of your program&rsquo;s native language.  The
language you use to build expressions is called the <em>working
language</em>.
