On a side note...
If you use prototypes and the sub appears on the bottom (or after the invocation), the prototype will not work as intended. You'll get a "main::subroutine called too early to check prototype" warning and the prototype will not/cannot be checked. When using prototypes, you'll need to either place the sub before its invocation or declare the sub and its prototype:
sub prototest($); # declare sub and prototype
prototest( 4 ); # dies if no param or more than 1 param is passed
sub prototest($){
print '1, 2, 3, ', @_;
}
-or-
sub prototest($){
print '1, 2, 3, ', @_;
}
prototest( 4 ); # dies if no param or more than 1 param is passed

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).
