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
|

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. The <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).
