Thanks for enlightening me! ;-)
I prefer your second example. The only problem with that example is that you've forgotten one single slash character at the end of tr:
$line += tr/ \t\r\n/c;
which must be:
$line += tr/ \t\r\n//c;
After fixing that, the sript works cool ;-)
I also realized that I can handle the situation using the command line:
$ tr [:space:] -d <ccount.pl | wc
0 1 69
Now I think that tr (in Perl or in shell) is a better way to get rid of unwanted characters, am I wrong?
P.S.: If Thelonious S. Monk programmed (in any language) woe to the ones who could maintain his code ;-)

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).
