In list context, the hash returns
('one', 1, 'two', 2, 'three', 3)
(but not necessarily in that order). So
print(%db, "\n");
is the same as
print('one', 1, 'two', 2, 'three', 3, "\n");
When you pass a list to print, it does
join($,, LIST)
So the above print is equivalent to
print(join($,, 'one', 1, 'two', 2, 'three', 3, "\n"));
However, in scalar context, the hash some information about its buckets. To do emulate the behaviour of print, do
$db = join($,, %db);

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).
