I'd do it with an unless statement. It allows you to keep things almost as with the or but without the pitfalls.
unless ($self->{ftp}->put($origin, $target)) {
$msg = $self->{ftp}->message();
$cod = $self->{ftp}->code();
print "$cod: $msg\n";
return 1;
}
You can even leave out the parenthesis on the print statement ;-)

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).
