**Specification**

- *Alias:* None

- *Arguments:* None


**Description**



When this keyword is used, parameters files will be written in JSON 
format, which is explained :ref:`here <variables:parameters:json>`.
JSON format files can be decoded by many programming languages,
which may make them easier to work with than standard or APREPRO
format parameters files.




**Examples**



.. code-block::

    interface
      fork
      analysis_drivers 'driver.py'
      parameters_file = "params.in"
      results_file = "results.out"
      parameters_format
