Thanks hippo, I will give this a shot. I'm reading the documentation on the /g modifier but do not see yet how this will work. If the issue was that there were two a's in 'lama', what does it mean that when I ran the original code, 'aaron' successfully matched 'baron' as it should have? Guessing it's to do with the fact that in this latter case, the repeated instance of 'a' comes after rather than before the a/b swap position, unlike 'lama' and 'lamb'. How this plays into the regex though, I don't yet see.

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).
