There is a "stupid-simple" way to write this as a sub which returns True or False. Something like:
$a = <file>;
while ($b = <file>) {
if (($a cmp $b) > 0) return false;
$a = $b;
}
return true;
There. Anyone can understand that in about ten seconds, and debug it and patch it forever. Go ahead and write as many "redundant" functions like this as you care to, because the day might will come when one of them has to be just a little different ... and you prepared for that, so what could be a big change in "clever" code is a small one instead, just as it should be. Your successors will thank you.

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).
