Thank you for all your gentle answers, but if I run this:
#!/usr/bin/perl
print "Content-type: text/html\n\n";
srand();
$fil="ch";
open(OUT, '>>'.$fil);
for($i=1;$i<10001;$i++){
$j=int(rand(20000))+440000;
$k=substr(pack('l>',$j),1);
print OUT $k;
}
close(OUT);
print "DONE !";
it produces one file with a variable length, but always greater than 30000 characters (for exemple 30045) !
So I suppose something is wrong in the pack line coding...

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.
