program main
open(99,form="formatted",access="stream")
write (99,'(A)',advance="no") 'a'
write (99,'(A)',advance="no") 'b'
close (99)
end program main
should write a single line to file 99, with
the contents
ab
Right now, it writes
a
b

------- Comment #1 from jvdelisle at gcc dot gnu dot org 2007-12-04 07:30 -------
hint: I think bytes_written needs to be calculated slightly differently so that
the CR/LF is added at the end when the file is closed in close.c (close_unit_1)
stream POS specifiers are base 1 and RECL is base 0.

* io/io.h: Add previous_nonadvancing_write to gfc_unit.
Add prototype for finish_last_advance_record.
* io/file_pos.c (st_backspace): Generate error if backspace is
attempted for direct access or unformatted stream.
If there are bytes left from a previous ADVANCE="no", write
them out before performing the backspace.
(st_endfile): Generate error if endfile is attempted for
direct access.
If there are bytes left from a previous ADVANCE="no", write
them out before performing the endfile.
(st_rewind): Generate error if rewind is attempted for
direct access.
* unit.c (close_unit_1): Move functionality to write
previously written bytes to...
(finish_last_advance_record): ... here.
* transfer.c (data_transfer_init): If reading, reset
previous_nonadvancing_write.
(finalize_transfer): Set the previous_noadvancing_write
flag if we are writing and ADVANCE="no" was specified.
Only call next_record() if advance="no" wasn't specified.
