    # Description of argument(s):
    # ffdc_function_list  A colon-delimited list naming the kinds of FFDC that

    #                     'Get FFDC Method Desc' (e.g. "FFDC Generic Report").

    # ffdc_function_list  See ffdc_function_list description in

    #                     in this case, it should be a list rather than a
