#!/usr/bin/perl -w
use strict;
my $foo_text .= $_ while (<DATA>);
print "$foo_text\n";
__DATA__
foo wears foo shoes at the foo store.
produces the following error:
Use of uninitialized value at foo.pl line 4, <DATA> chunk 1 (#1)
Any one know what's going on here? Please, to aid in my learning/understanding of
Perl a reason why this does not work and not a solution would be very much
appreciated.

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).

Want more info? How to link or
or How to display code and escape characters
are good places to start.
