steph_bow,
The naive way to do this might look like:
#!/usr/bin/perl
use strict;
use warnings;
while (<DATA>) {
chomp;
my @col = split /;/;
push @col, '' for @col .. 2;
print join ';', @col;
print "\n";
}
__DATA__
a;3
b;2;3
c;5;4
d;6
A less naive solution would use a module from CPAN such as Text::CSV or Text::xSV. To understand why that is a better approach, take a few minutes with Super Search.
Update: As noted by tye in the CB, this solution was originally not tested. I added chomp and changed @col .. 3; to @col .. 2;

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).
