<div><p>A trace is the process of recording the sequence in which the statements
|
|
in a program are processed. </p>
|
|
<div class="section"> <p>A trace differs from a breakpoint in that you are not given control
|
|
during the trace. The system records the traced statements that were processed.
|
|
However, the trace information is not automatically displayed
|
|
when the program completes processing. You must request the display of trace
|
|
information using the <span class="cmdname">Display Trace Data (DSPTRCDTA)</span> command.
|
|
The display shows the sequence in which the statements were processed and,
|
|
if requested, the values of the variables specified on the <span class="cmdname">Add Trace
|
|
(ADDTRC)</span> command.</p>

Adding a trace consists of specifying what statements are to be traced and, if you want, the names of program variables.</li>

<li class="ulchildlink"><strong><a href="instp.htm">Use instruction stepping</a></strong><br />

You can step through the instructions of a program by using the <span class="cmdname">Start
