 683         DELIM_UNSPECIFIED set inquire return string to "NONE".
 684         * io/list_read.c (read_character): In the case of DELIM_NONE and
 685         namelists, complete the character read using the namelist
 686         variable length.
 687         * io/open.c (new_unit): Don't set delim status to none if not
 688         specified so that DELIM_UNSPECIFIED can be used later.
 689         * io/transfer.c (data_transfer_init): For namelist I/O, if the
 690         unit delim status is unspecified set the current status to quote.
 691         Otherwise, set current status to the unit status.
 692         * io/unit.c (get_internel_unit, init_unit): Remember to set
 693         flags_delim initially to DELIM_UNSPECIFIED so defaults come out
 694         correctly.
 695         * io/write.c (write_character): Add a new function argument
 696         "mode" to signify that raw output is to be used vs output with
 697         delimiters. If the mode is set to DELIM (1) proceed with
 698         delimiters. (list_formatted_write_scalar): Write the separator
 699         only if a delimiter was previously specified. Update the call to
 700         write_character with the mode argument given.
 701         (namelist_write_newline): Use the mode argument. (nml_write_obj):
 702         Use the mode argument. Remove use of tmp_delim. Write the
 703         semi-colon or comma correctly only when needed with using
 704         delimiters. Cleanup whitespace.
 705         (namelist_write): If delim is not specified in namelist I/O,
 706         default to using quotes. Get rid of the tmp_delim variable and
 707         use the new mode argument in write_character.
