For example, the <code>prompt</code> input type features the following annotations: </p> <div class="smallexample"> <pre class="smallexample">^Z^Zpre-prompt ^Z^Zprompt ^Z^Zpost-prompt </pre></div> <p>The input types are </p> <dl compact="compact"> <dd><a name="index-pre_002dprompt-annotation"></a> <a name="index-prompt-annotation"></a> <a name="index-post_002dprompt-annotation"></a> </dd> <dt><code>prompt</code></dt> <dd><p>When <small>GDB</small> is prompting for a command (the main <small>GDB</small> prompt). </p> <a name="index-pre_002dcommands-annotation"></a> <a name="index-commands-annotation"></a> <a name="index-post_002dcommands-annotation"></a> </dd> <dt><code>commands</code></dt> <dd><p>When <small>GDB</small> prompts for a set of commands, like in the <code>commands</code> command.
