| <h4 class="subsubsection">15.4.8.9 <small>GDB</small> and Modula-2</h4> |
| |
| <p>Some <small>GDB</small> commands have little use when debugging Modula-2 programs. |
| Five subcommands of <code>set print</code> and <code>show print</code> apply |
| specifically to C and C<tt>++</tt>: ‘<samp>vtbl</samp>’, ‘<samp>demangle</samp>’, |
| ‘<samp>asm-demangle</samp>’, ‘<samp>object</samp>’, and ‘<samp>union</samp>’. The first four |
| apply to C<tt>++</tt>, and the last to the C <code>union</code> type, which has no direct |
| analogue in Modula-2. |
| </p> |
| <p>The <code>@</code> operator (see <a href="Expressions.html#Expressions">Expressions</a>), while available |
| with any language, is not useful with Modula-2. Its |
| intent is to aid the debugging of <em>dynamic arrays</em>, which cannot be |
| created in Modula-2 as they can in C or C<tt>++</tt>. However, because an |
| address can be specified by an integral constant, the construct |
| ‘<samp>{<var>type</var>}<var>adrexp</var></samp>’ is still useful. |
| </p> |
| <a name="index-_0023-in-Modula_002d2"></a> |
| <p>In <small>GDB</small> scripts, the Modula-2 inequality operator <code>#</code> is |
| interpreted as the beginning of a comment. Use <code><></code> instead. |
