<a name="1206756"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">This section describes the debugging facility provided by <strong>st20run</strong>, which can be used to debug application software. A debugging process runs on the host, while the application may run on a target ST20 or a simulator.</font>
</p>
<p>
<a name="1206757"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The debugger allows the user to explore the state of the application. The debugger is controlled by a combination of:</font>
</p>
<ul>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206758"> </a>using the graphical interface interactively,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206759"> </a>entering options on the <strong>st20run</strong> command line, and,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206760"> </a>using the command language either interactively or using scripts.</font></p>
</ul>
<p>
<a name="1206761"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The debugger supports symbolic debugging of C and C++ code and assembler code. It provides the following facilities:</font>
</p>
<ul>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206762"> </a>reading and writing to memory and registers,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206763"> </a>a breakpoint facility that allows the program to be stopped when code is about to be executed or selected variables have been written to or read from,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206764"> </a>a single stepping facility that allows a task to be single stepped at the source level or at the assembly code level,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206765"> </a>a stack trace facility,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206766"> </a>the ability to display the values of variables and display memory,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206767"> </a>a simple interpreter to enable structured C or C++ variables to be displayed,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206768"> </a>a programmable command language that allows complex breakpoints to be set and enables debugging scripts to be generated,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206769"> </a>support for multiple connections, multiple programs and multi-tasking applications,</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206770"> </a>profiling,</font></p>

</ul>
<p>
<a name="1206772"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">Depending on the run-time operating system used, a facility to find the tasks of a program is also provided.</font>

<a name="1206773"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The user controls, through the debugger, when the application runs and when it stops.
