title: Export CSV from Mainframe DB2 in batch mode
body: <p>how can I export in a CSV file the result of a SELECT query from Mainframe DB2 in Batch mode?
  I have tried the FILE MANAGER online mode and it works but I need to use the batch mode for a better performance. 
  I can also use ISQL but I don't know which parameters I have to use to create a CSV file.
  Thanks</p>
