title: ERRORLEVEL conditions
body: <p>Should this logic not send 0 and 1 error levels to the 'mailerror' subroutine and simply exit if they are 0 or 1 errors?</p>
  
  <pre><code>IF %ERRORLEVEL% NEQ 0 (
      IF %ERRORLEVEL% NEQ 1 (   
      SET BODY="exit error code from Backup of RAD file = %ERRORLEVEL%."
      goto mailerror
      )
   ) ELSE (
   EXIT
   )
  </code></pre>
