- <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 ‘<samp>middle</samp>’ if <var>addr</var> is in the middle of the
- line, or ‘<samp>beg</samp>’ 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. <var>addr</var> is in the form ‘<samp>0x</samp>’
- followed by one or more lowercase hex digits (note that this does not
- depend on the language).
