<h1 class="topictitle1"> Set and remove unconditional breakpoints</h1>
|
||
|
|
<div><p>There are a variety of ways to set and remove unconditional breakpoints.</p>
|
||
|
|
<div class="section"><p>You can set or remove an unconditional breakpoint by using: </p>
|
||
|
|
<ul><li>F6 (Add/Clear breakpoint) from the Display Module Source display</li>
|
||
|
|
<li>F13 (Work with Module Breakpoints) from the Display Module Source display</li>
|
||
|
|
<li>The BREAK debug command to set a breakpoint</li>
|
||
|
|
<li>The CLEAR debug command to remove a breakpoint</li>
|
||
|
|
</ul>
|
||
|
|
<p>The simplest way to set and remove an unconditional breakpoint
|
||
|
|
is to use F6 (Add/Clear breakpoint) from the Display Module Source display.
|
||
|
|
To set an unconditional breakpoint using F6, place your cursor on the line
|
||
|
|
to which you want to add the breakpoint and press F6. An unconditional breakpoint
|
||
|
|
is then set on the line. To remove an unconditional breakpoint, place your
|
||
|
|
cursor on the line from which you want to remove the breakpoint and press
|
||
|
|
F6. The breakpoint is then removed from the line.</p>
|
||
|
|
<div class="p">Repeat the previous
|
||
|
|
steps for each unconditional breakpoint you want to set. <div class="note"><span class="notetitle">Note:</span> If the line
|
||
|
|
on which you want to set a breakpoint is not a runnable statement, the breakpoint
|
||
|
|
is set at the next runnable statement.</div>
|
||
|
|
</div>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>After the breakpoints are set, press F3 (Exit) to leave the Display
|
||
|
|
Module Source display. You can also use F21 (Command Line) from the Display
|
||
|
|
Module Source display to call the program from a command line.</p>
|
||
|
|
<p>Call
|
||
|
|
the program object. When a breakpoint is reached, the program stops and the
|
||
|
|
Display Module Source display is shown again. At this point, you can evaluate
|
||
|
|
variables, set more breakpoints, and run any of the debug commands.</p>
|
||
|
|
<p>An
|
||
|
|
alternate method of setting and removing unconditional breakpoints is to use
|
||
|
|
the BREAK and CLEAR debug commands.</p>
|
||
|
|
<p>To set an unconditional breakpoint
|
||
|
|
by using the BREAK debug command, type the following on the debug command
|
||
|
|
line: </p>
|
||
|
|
<pre>BREAK line-number</pre>
|
||
|
|
<p><span class="synph"><span class="var">Line-number</span></span> is the line number in
|
||
|
|
the currently displayed view of the module object on which you want to set
|
||
|
|
a breakpoint.</p>
|
||
|
|
<p>To remove an unconditional breakpoint by using the CLEAR
|
||
|
|
debug command, type the following on the debug command line: </p>
|
||
|
|
<pre>CLEAR line-number</pre>
|
||
|
|
<p><span class="synph"><span class="var">Line-number</span></span> is the line number in
|
||
|
|
the currently displayed view of the module object from which you want to remove
|
||
|
|
a breakpoint.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>If using the statement view, there is no line numbers displayed.
|
||
|
|
To set unconditional breakpoints in the statement view, type the following
|
||
|
|
on the debug command line:</p>
|
||
|
|
<pre>BREAK procedure-name/statement-number</pre>
|
||
|
|
<p><span class="synph"><span class="var">Procedure-name</span></span> is the name of your
|
||
|
|
CL module. <span class="synph"><span class="var">Statement-number</span></span>(from the compiler listing)
|
||
|
|
is the statement number where you wanted to stop.</p>
