I also tried using sprintf, but if the data is longer than intended, the line becomes too long.
You do know you can specify the maximum width?
printf "%2.2s>%32.32s<\n",
$_, 'x' x $_ for 30 .. 34, 99..101;;
30> xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
31> xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
32>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
33>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
34>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
99>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
10>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<
10>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<

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).
