<h3>Introduction</h3>
|
|
The <B>inspector</B> is the simplest tool to visualize the value of
|
|
Scheme variables. To inspect the variable <I>my-variable</I>, just type:
|
|
<pre>
|
|
STk> (inspect 'my-variable)
|
|
</pre>
|
|
<p>
|
|
A variable can also be inspected in particular environment as in:
|
|
<pre>
|
|
STk> (inspect 'var (procedure-environment foo))
|
|
</pre>
|
|
To uninspect a variable, just enter the following expression:
|
|
<pre>
|
|
(uninspect 'var)
|
|
</pre>
|
|
or select the <B>Uninspect</B> option in the Icon menu associated
|
|
with the object line inspector.
