------- Comment #1 from jvdelisle at gcc dot gnu dot org 2006-09-28 23:23 -------
Please note that with formatted stream I/O we implicitly write a /n or /r/n in
the next_record_w () function in transfer.c depending on the system. I think
this meets the intent.
Now an issue I see is what if we want to explicitly write a /n on this system?
There would be no way to do that if we translate it to /n/r. I am not sure the
intent of the committee was to restrict this in this way, but allow it in the
case of formatted end of record.
I have not tried this, but if I write out a formatted string with one character
/n I wonder if we we get /n/r/n with current gfortran.
I am not agreeing or diagreeing here. You have raised a good question here.

------- Comment #2 from jvdelisle at gcc dot gnu dot org 2006-09-28 23:36 -------
Another thought occurs to me. With formatted stream I/O the newline is handled
automatically for the user. However, there is nothing to say someone would not
want to use unformatted stream I/O to write human readable files. In that
case, you would want the result of newline to give the /r/n or /n on the
respective systems.
Based on this thinking, the translation, if any, should be done for unformatted
I/O and only when the NEWLINE function is explicitly used.
Clealy we have a case where the standard may not be all that clear.

OK, I confess I sen a note to Richard Maine to doble check on this. Brooks has
it absolutely right. So, I will see what I can come up with for you. If its a
requirement of the standard, it is not an enhancement.

------- Comment #5 from jvdelisle at gcc dot gnu dot org 2006-10-09 03:07 -------
Created an attachment (id=12398)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=12398&action=view)
Preliminaey patch for STREAM formatted read.
There is a related problem with formatted stream read:
program stream
implicit none
character(len=50) :: r1,r2
open(10,file='test.dat',form='formatted',access='stream',status='old')
read(10,'(a)') r1
read(10,'(a)') r2
print *, ':',trim(r1),':'
print *, ':',trim(r2),':'
end program stream
I have a preliminary patch for this that I would appreciate some testing on
cygwin or other CR-LF type system. This is for the read only.

I expect the test case streamio_4.f90 to fail with the preliminary patch. I
have not completed the formatted stream write portion. What I need confirmed
is that when reading that the file is being positioned correctly when a CR-LF
is encountered.

------- Comment #8 from jvdelisle at gcc dot gnu dot org 2006-10-13 01:41 -------
Note: I believe it may be necessary to explicitly inject a '\r' when a '\n' is
embedded in a string. I am not quite set up to test this yet here. So I would
much appreciate if some one can do that, while I continue to study that part.
The patch submitted in comment #7 is fully test on '\n' only system.

There is one final patch to go before closing this PR. I am testing it now and
developing a test case. This is the part that converts LF to CR-LF for
FORMATTED STREAM IO on those systems that #define HAVE_CRLF.
