ikegami,
With all due respect, the topic is not about Perl's definition of byteorder, but the definition of and examples for little-endian and big-endian in the on-line documentation for Perl's 'pack' function. Perl's byteorder is academic!
Please see the following from a RS/6000 with AIX 5.2 operating system:

and
byteorder='4321';
and
pyrperl -e '$p=pack("N",16909060); print unpack("H8",$p),"\n";'

Until now, I did not know that the RS/6000 has a software switch on the motherboard to indicate running in
little-endian or
big-endian. When I read the Camel book, and it said that the "N" parameter of 'pack' put the result in
Network or
big-endian format, I knew what that meant and it didn't have an example. My original problem was with the on-line documentation.
In goggling this, many authors seem to be guessing!

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).
