|
|
<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
|
||
|
|
‘<samp>0x1ae</samp>’, while in Modula-2 they appear as ‘<samp>1AEH</samp>’.
|
||
|
|
</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’s
|
||
|
|
native language, and allowing <small>GDB</small> to output values in a manner
|
||
|
|
consistent with the syntax of your program’s native language. The
|
||
|
|
language you use to build expressions is called the <em>working
|
||
|
|
language</em>.
