oct , perlquote, http://perldoc.perl.org/perlrebackslash.html#Octal-escapes, perlnumber, octal $ perl -le " print 041 "
33
$ perl -le " print chr 041 "
!
$ perl -le " print chr 33 "
!
$ perl -le " print ord q{!} "
33
So the integer 33 is written in octal as 041, and if you chr 33 you get !
Make sense?
In a double quoted string 041 is 041, but \041 is chr 33 (octal escape) $ perl -le " print qq{041} "
041
$ perl -le " print qq{\041} "
!

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).
