The following is an RPG/LE free-form definition for the IBM API Error Code data structure.

The API Error Code data structure

      * IBM API Error Code parameter -- ERRC0100 format
      * NOTE: If supported, including this data structure as a parameter in your
      *       API calls is equivalent to using MONITOR to trap hard errors.  If
      *       an error occurs, it allows the API to pass back the error message
      *       id and any replacement data associated with that message id.
