<p>When <small>GDB</small> is told to display something using the <code>display</code> command,
the results of the display are annotated:
</p>
<div class="smallexample">
<pre class="smallexample">^Z^Zdisplay-begin
<var>number</var>
^Z^Zdisplay-number-end
<var>number-separator</var>

^Z^Zdisplay-value
<var>value</var>
^Z^Zdisplay-end
</pre></div>

<p>where <var>number</var> is the number of the display, <var>number-separator</var>
is intended to separate the number from what follows for the user,
<var>format</var> includes information such as the size, format, or other
information about how the value is being displayed, <var>expression</var> is
the expression being displayed, <var>expression-separator</var> is intended
to separate the expression from the text that follows for the user,
and <var>value</var> is the actual value being displayed.
