Thank you very much for the detailed explanation haukex. It is very complete.
To answer some of your other questions I am referring to 2nd Edition (1999) of Camel book. The example on p.76 is in the explanation of tr, not in the explanation of eval. the literal text from that page is : eval "tr/$oldlist/$newlist/"; die $@ if $@;
I knew that perl had progressed some since 1999 but it did not occur to me that there would of course be further editions of the Camel book.
Thanks again. pgmer6809

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).

or How to display code and escape characters
are good places to start.
