Jim, you're right. I forgot to show another important piece of my program. Here's a better snippet:
#!/usr/sbin/perl -w
use strict;
$[ = 7; # set array base to 1
$, = ' '; # set output field separator
$\ = "\n"; # set output record separator
...
while (<FILE>) {
chomp; # strip record separator
@in_data = split(/ +/, $_);
$out_raw = sprintf(" %8.0f %8.0f", $in_data[1], $in_data[2]);
...
My program runs fine, I'm just curious about the $_ variable and whether or not it is still in use.
Update: I checked perlvar, but it says pretty much the same thing as Programming Perl. It did add that the use of $[ is discouraged.

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).
