I think it can be as simple as this: use Modern::Perl;
open my $WORDLIST, '<', './wordlist.txt' or die $!;
my $available = 'AABCDEF';
$available = join '?', sort split '', $available;
$available .= '?';
while (<$WORDLIST>) {
chomp;
my $sorted = join '', sort split '';
say if $sorted =~ /^$available$/io;
}
Running this script with your 'AABCDEF' gives me the following results: abe
ace
aced
baa
bad
bade
be
bead
bed
cab
cad
cade
cafe
dab
dace
deaf
deb
decaf
fab
facade
face
faced
fad
fade
fed
I use a 58,000 elements wordlist and it needed less than a few seconds to generate this result.
CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

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).
