You could try using backspaces to back up over the previous number and overwrite it. Or use the ANSI cursor escape sequences to move back to the start of the line or directly to the position on the line and overwrite.
The following code is good Perl, but it does work.
#!e:\perl\bin\perl.exe -w
use strict;
use warnings;
use diagnostics;
for( my $n=1; $n<1000; $n++) {
my $back = length $n;
print $n, substr "\b\b\b\b", 0, $back;
}

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.
