($name, $city, $state, $zip) = (split / /, $_)[4,5,6,8];
I think the OP is probably with the default behavioiur of split() - nothing to be gained by spelling it out.
It would be very unusal in real code that in an assignement statement such as the one above you would really want to overwrite the values of four existing variables. It would be far more common that this is the point in the code at which these four variables would be introduced.
Newcommers to Perl often have problems with variable declaration. When presenting issolated code fragments all assignment statements should have a my() if is more likely than not that they would need one in any well-written real code.
my ($name, $city, $state, $zip) = (split)[4,5,6,8];

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).
