 <p>Line numbers service associates locations in the source files with the corresponding
 machine instruction addresses in the executable object.</p>

 <p>Line number information is searched in symbol files of a debug context.
 The symbol file list is handled by <a href='TCF Service - Memory Map.html'>Memory Map Service</a>.</p>

 <p>Results of line information searches are arrays of Code Area objects. Code Area represents a continues area in source text mapped to
 continues range of code addresses. Code Area data object is collection of area properties.</p>

 <p>Lines are numbered beginning at 1.</p>

 <p>Columns are numbered beginning at 1. The value 0 is reserved to indicate that a code area begins at the "left edge" of the line.
    Absence of column property means same as value 0.</p>

 <p>Predefined Code Area properties are:</p>
 <ul>
     <li><code><b><font face="Courier New" size=2 color=#333399>"SLine" : <i>&lt;number&gt;</i></font></b></code>
       - line number of the start of the area in the source file.

     <li><code><b><font face="Courier New" size=2 color=#333399>"SCol" : <i>&lt;number&gt;</i></font></b></code>
       - column number of the start of the area in the source file.

     <li><code><b><font face="Courier New" size=2 color=#333399>"SAddr" : <i>&lt;number&gt;</i></font></b></code>
       - address of the start of the area in memory.

     <li><code><b><font face="Courier New" size=2 color=#333399>"ELine" : <i>&lt;number&gt;</i></font></b></code>
       - line number of the end of the area in the source file.

     <li><code><b><font face="Courier New" size=2 color=#333399>"ECol" : <i>&lt;number&gt;</i></font></b></code>
       - column number of the end of the area in the source file.

     <li><code><b><font face="Courier New" size=2 color=#333399>"EAddr" : <i>&lt;number&gt;</i></font></b></code>
       - address of the end of the area in memory.

     <li><code><b><font face="Courier New" size=2 color=#333399>"NAddr" : <i>&lt;number&gt;</i></font></b></code>
       - address of the next area in the source file.

     <li><code><b><font face="Courier New" size=2 color=#333399>"File" : <i>&lt;string&gt;</i></font></b></code>
       - name of the source file corresponding to the area. It can be relative to "Dir".

     <li><code><b><font face="Courier New" size=2 color=#333399>"Dir" : <i>&lt;string&gt;</i></font></b></code>
       - directory name of of the source file corresponding to the area.

     <li><code><b><font face="Courier New" size=2 color=#333399>"ISA" : <i>&lt;number&gt;</i></font></b></code>
       - an integer whose value encodes the applicable instruction set architecture for the area.

     <li><code><b><font face="Courier New" size=2 color=#333399>"IsStmt" : <i>&lt;boolean&gt;</i></font></b></code>
       - a boolean indicating that the area is a recommended breakpoint location.
       A recommended breakpoint location is intended to "represent" a line, a statement and/or a semantically distinct subpart of a statement.

     <li><code><b><font face="Courier New" size=2 color=#333399>"BasicBlock" : <i>&lt;boolean&gt;</i></font></b></code>
       - a boolean indicating that the area is the beginning of a basic block.

     <li><code><b><font face="Courier New" size=2 color=#333399>"PrologueEnd" : <i>&lt;boolean&gt;</i></font></b></code>
       - a boolean indicating that the area is one (of possibly many) where execution should be suspended for an entry breakpoint of a function.

     <li><code><b><font face="Courier New" size=2 color=#333399>"EpilogueBegin" : <i>&lt;boolean&gt;</i></font></b></code>
       - a boolean indicating that the area is one (of possibly many) where execution should be suspended for an exit breakpoint of a function.

     <li><code><b><font face="Courier New" size=2 color=#333399>"OpIndex" : <i>&lt;number&gt;</i></font></b></code>
       - an integer representing the index of an operation within a VLIW instruction.
       The index of the first operation is 0. For non-VLIW architectures, this is either 0 or absent.

     <li><code><b><font face="Courier New" size=2 color=#333399>"Discriminator" : <i>&lt;number&gt;</i></font></b></code>
       - an integer identifying the block to which the area belongs.
       Discriminator values are assigned arbitrarily by the debug information producer and serve to distinguish among
       multiple blocks that may all be associated with the same source file, line, and column.
       Where only one block exists for a given source position, the discriminator value should be either 0 or absent.

     <li><code><b><font face="Courier New" size=2 color=#333399>"NStmtAddr" : <i>&lt;number&gt;</i></font></b></code>
       - address of the next recommended breakpoint location (start of statement).
 </ul>

	<p>Line numbers service associates locations in the source files with the corresponding
	machine instruction addresses in the executable object.</p>

	<p>Line number information is searched in symbol files of a debug context.
	The symbol file list is handled by <a href='TCF Service - Memory Map.html'>Memory Map Service</a>.</p>

	<p>Results of line information searches are arrays of Code Area objects. Code Area represents a continues area in source text mapped to
	continues range of code addresses. Code Area data object is collection of area properties.</p>

	<p>Lines are numbered beginning at 1.</p>

	<p>Columns are numbered beginning at 1. The value 0 is reserved to indicate that a code area begins at the "left edge" of the line.
	Absence of column property means same as value 0.</p>

	<p>Predefined Code Area properties are:</p>
	<ul>
	<li><code><b><font face="Courier New" size=2 color=#333399>"SLine" : <i><number></i></font></b></code>
	- line number of the start of the area in the source file.

	<li><code><b><font face="Courier New" size=2 color=#333399>"SCol" : <i><number></i></font></b></code>
	- column number of the start of the area in the source file.

	<li><code><b><font face="Courier New" size=2 color=#333399>"SAddr" : <i><number></i></font></b></code>
	- address of the start of the area in memory.

	<li><code><b><font face="Courier New" size=2 color=#333399>"ELine" : <i><number></i></font></b></code>
	- line number of the end of the area in the source file.

	<li><code><b><font face="Courier New" size=2 color=#333399>"ECol" : <i><number></i></font></b></code>
	- column number of the end of the area in the source file.

	<li><code><b><font face="Courier New" size=2 color=#333399>"EAddr" : <i><number></i></font></b></code>
	- address of the end of the area in memory.

	<li><code><b><font face="Courier New" size=2 color=#333399>"NAddr" : <i><number></i></font></b></code>
	- address of the next area in the source file.

	<li><code><b><font face="Courier New" size=2 color=#333399>"File" : <i><string></i></font></b></code>
	- name of the source file corresponding to the area. It can be relative to "Dir".

	<li><code><b><font face="Courier New" size=2 color=#333399>"Dir" : <i><string></i></font></b></code>
	- directory name of of the source file corresponding to the area.

	<li><code><b><font face="Courier New" size=2 color=#333399>"ISA" : <i><number></i></font></b></code>
	- an integer whose value encodes the applicable instruction set architecture for the area.

	<li><code><b><font face="Courier New" size=2 color=#333399>"IsStmt" : <i><boolean></i></font></b></code>
	- a boolean indicating that the area is a recommended breakpoint location.
	A recommended breakpoint location is intended to "represent" a line, a statement and/or a semantically distinct subpart of a statement.

	<li><code><b><font face="Courier New" size=2 color=#333399>"BasicBlock" : <i><boolean></i></font></b></code>
	- a boolean indicating that the area is the beginning of a basic block.

	<li><code><b><font face="Courier New" size=2 color=#333399>"PrologueEnd" : <i><boolean></i></font></b></code>
	- a boolean indicating that the area is one (of possibly many) where execution should be suspended for an entry breakpoint of a function.

	<li><code><b><font face="Courier New" size=2 color=#333399>"EpilogueBegin" : <i><boolean></i></font></b></code>
	- a boolean indicating that the area is one (of possibly many) where execution should be suspended for an exit breakpoint of a function.

	<li><code><b><font face="Courier New" size=2 color=#333399>"OpIndex" : <i><number></i></font></b></code>
	- an integer representing the index of an operation within a VLIW instruction.
	The index of the first operation is 0. For non-VLIW architectures, this is either 0 or absent.

	<li><code><b><font face="Courier New" size=2 color=#333399>"Discriminator" : <i><number></i></font></b></code>
	- an integer identifying the block to which the area belongs.
	Discriminator values are assigned arbitrarily by the debug information producer and serve to distinguish among
	multiple blocks that may all be associated with the same source file, line, and column.
	Where only one block exists for a given source position, the discriminator value should be either 0 or absent.

	<li><code><b><font face="Courier New" size=2 color=#333399>"NStmtAddr" : <i><number></i></font></b></code>
	- address of the next recommended breakpoint location (start of statement).
	</ul>
