To answer my own question (finally), the reason the last line of the loop "does nothing" is because thats the way I designed it! The list already contains all the lower-case alpha's, so trying to add more will do nothing! D'oh!
Of course, what I had intended to do was (0 == int(rand 4)) and $fifo1->( chr(65+rand 26) ); but I just couldn't see it!
Well It's better than the Abottoire, but Yorkshire!

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).
