       The function free_form disconnects form from its field array and  frees
       the storage allocated for the form.

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_CONNECTED
            The field is already connected to a form.

       E_SYSTEM_ERROR
            System error occurred, e.g., malloc failure.

       The function free_form returns one of the following:

       E_OK The routine succeeded.

       ported on Version 7 or BSD versions.
