Printing string with two columns
<p>I'm trying to print a string with two fixed columns.  For example, I'd like to be able to print:</p>

<pre><code>abc       xyz
abcde     xyz
a         xyz
</code></pre>

<p>What is the correct way to format the output string when printing to achieve this?  Also, how is this done before version 2.6 and after version 2.6?</p>
