Although ysth has a fix for the following issue, be careful using !/$position/ when grepping to remove unwanted elements, as unintended results may happen:
use strict;
use warnings;
my @priority = qw(RB1 RB2 FL1 FL11 FL2 QB1 QB2 TE1 WR1 WR2 DST);
my $position = 'FL1';
print "$_\n" for grep !/$position/, @priority;
Output:
RB1
RB2
FL2
QB1
QB2
TE1
WR1
WR2
DST
Note that elements 'FL1' and 'FL11' were removed. To avoid this, use either ysth's $_ ne $position or !/^$position$/ (which forces a complete--not just partial--match) when grepping in your script.

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).
