[Bug fortran/31199] write with t1 format gives wrong output

2007-03-19 Thread burnus at gcc dot gnu dot org

Current result:
 a = ABCDEFXXX
 b = ABCDEF
 c = ABCDEFXXX

Result by g95/ifort:
 ABCDEFXXX
 ABCDEFXXX
 ABCDEFXXX

Result by NAG f95, SUN and HP:
 ABCDEFXXX
 ABCXXDEF
 ABCDEFXXX

I think the latter is correct:

Section 9.2.3.3 of the Fortran 2003 standard:
For a formatted stream output statement, ... the terminal point of
the file is set to the highest-numbered position to which data was
transferred by the statement.

(Thanks to Ian Hounam/NAG for pointing out.)

 Result by g95/ifort:

You can probably add xlf to this list (should be checked
on a recent version).

 You can probably add xlf to this list

and Portland Group Fortran.

Found it.  In the case of advance=no we are not saving the maximum position
reached to be used by the following write statement.  This one is subtle.

Current result:
 a = ABCDEFXXX
 b = ABCDEF
 c = ABCDEFXXX
Expected (g95/ifort):
 ABCDEFXXX
 ABCDEFXXX
 ABCDEFXXX
(NAG f95 has:
 ABCDEFXXX
 ABCXXDEF
 ABCDEFXXX
)

I will work this one.  I want to review the standard.  I think we are
truncating and I am not so sure this has to do with the t1 format specifier. 
We'll see.
