title: Simple Ruby program does not produce output
body: <p>I wrote a basic ruby program with TextMate in Mac OS:</p>
  <pre><code>def hello
    puts &quot; This works!&quot;
  end
  </code></pre>
  <p>name it <code>Check-it.rb</code></p>
  <p>I open a Terminal session, <code>cd</code> to the directory where the program is stored.</p>
  <p>Then I type</p>
  <pre><code>ruby Check-it.rb
  </code></pre>
  <p>And nothing appears.</p>
  <pre><code>ruby -v
  </code></pre>
  <p>shows me the version, so it's there.
  But with this and every other Ruby program, nothing appears.</p>
