<h3>Command If True Then</h3>

<p>
Using a <i>Logical Expression (LE) </i>, this command lets you select the execution of a set of commands (it can be just one)
according to the logical result of the expression <tt>LE</tt>.
Symbolically: <i>If</i> <tt>LE</tt> to be true, <i>then</i> execute commands.
<br/>
Optionally, a <i>else</i> can be used, that is, if the
logical expression results false, a second set of commands will be executed.
Symbolically:
<i>IF</i> <tt>LE</tt> to be true, <i>then</i> execute true_commands, <i>else</i> execute false_commands.
