<p>The following annotation is used instead of displaying source code:
</p>
<div class="smallexample">
<pre class="smallexample">^Z^Zsource <var>filename</var>:<var>line</var>:<var>character</var>:<var>middle</var>:<var>addr</var>
</pre></div>

<p>where <var>filename</var> is an absolute file name indicating which source
file, <var>line</var> is the line number within that file (where 1 is the
first line in the file), <var>character</var> is the character position
within the file (where 0 is the first character in the file) (for most
debug formats this will necessarily point to the beginning of a line),
<var>middle</var> is &lsquo;<samp>middle</samp>&rsquo; if <var>addr</var> is in the middle of the
line, or &lsquo;<samp>beg</samp>&rsquo; if <var>addr</var> is at the beginning of the line, and
<var>addr</var> is the address in the target program associated with the
source which is being displayed.  The <var>addr</var> is in the form &lsquo;<samp>0x</samp>&rsquo;
followed by one or more lowercase hex digits (note that this does not
depend on the language).
