what do you mean by "delay use"? Do you probably mean sleep? this function can cause the script to pause for the amount of seconds specified or forever if no seconds were specified. Consider this very simple example:
for($num=5;$num>0;$num--){
print "$num\n";
sleep 2;
}
It'd take a while after printing the current value of $num and looping once again as affected by the duration of time provided in the EXPR to sleep. Best of luck...

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
