title: Lua is not producing output file
body: <p>I execute the code below but it doesn't create an output file (at least on the directory where the *.lua is)</p>
  
  <pre><code> file = io.open("output.txt","w")
  io.output(file)
  io.write("hello, reader!")
  io.close(file)
  </code></pre>
  
  <p>I am using ZeroBrane Studio on Windows, if that helps</p>
