Thank you for that explaination. So if I am reading it right, then the would following be true?
The following functions set the value of the return to 'default' by default. Then if was a parameter passed, $value gets set to that parameter. The differences
between the two are:
- The juxteposition of the shift() statement and 'default'
- The use of the '||' and 'or' operators
sub setValue_takeOne{
my $value = shift() || 'default';
return $value;
}
sub setValue_takeTwo{
my $value = 'default' or shift();
return $value;
}

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).
