<div class="section"><div class="p">You can also use the EVAL debug command to determine the value
|
||
|
|
of a variable. To display the value of a variable using the EVAL debug command,
|
||
|
|
type the following on the debug command line: <pre>EVAL variable-name</pre>
|
||
|
|
</div>
|
||
|
|
<p><span class="synph"><span class="var">Variable-name</span></span> is
|
||
|
|
the name of the variable that you want to display. The value of the variable
|
||
|
|
is shown on the message line if the EVAL debug command is entered from the
|
||
|
|
Display Module Source display and the value can be shown on a single line.
|
||
|
|
If the value cannot be shown on a single line, it is shown on the Evaluate
|
||
|
|
Expression display.</p>
|
||
|
|
<p>For example, to display the value of the variable <span class="synph"><span class="var">&DAYOFWK</span></span>;
|
||
|
|
on line 7 of the module object shown in the example above, type: </p>
|
||
|
|
<pre>EVAL &DAYOFWK</pre>
|
||
|
|
<p>The message line of the Display Module Source display shows <samp class="codeph">&DAYOFWK
|
||
|
|
= 3.</samp> as in the example above.</p>
|
||
|
|
<p>The scope of the variables used
|
||
|
|
in the EVAL command is defined by using the QUAL command. However, you do
|
||
|
|
not need to specifically define the scope of the variables contained in a
|
||
|
|
CL module because they are all of global scope.</p>
