This method retrieves the next record from the file.

  1. Don't lock (optional) - Pass Boolean true to avoid locking the record if the file is open for update/delete. If this parameter is set to Boolean false or omitted records will be locked for update/delete files.

  3. Input data structure (optional) - A Profound.js data structure reference. If specified, the referenced data structure will be populated with the record data. If the data structure is not qualified, you must wrap the parameter with the pjs.ds() API.

  • message - The message text.
  • error - The message id.
  • help - The message help text.
