title: MSDN about stored procedure default return value
body: <p>Could anyone point exactly where MSDN says thet every user stored procedure returns 0 by default if no error happens? In other words, could I be sure that example code given below when being a stored procedure</p>
  
  <pre><code>IF someStatement
  BEGIN
    RETURN 1
  END
  </code></pre>
  
  <p>should always return zero if someStatement is false and no error occurs?</p>
  
  <p>I know that it actually works this way, but I failed to find any explicit statement about this from Microsoft.</p>
