title: Oracle SQL Developer ver. 4.0.3.16 (TRIMSPOOL not supported)
body: <p>I tried using the command 'SET TRIMSPOOL ON' to output a query to a text file without trailing spaces, but, the command was just skipped.</p>
  
  <p>Script output says:</p>
  
  <pre>
  SQLPLUS Command Skipped: set TRIMSPOOL ON
  </pre>
  
  <p>Do I need to update anything to make this command work?
  My SQL Developer version is 4.0.3.16.</p>
