Hi Matthieu,
Sorry but I missed that.
Anyway I have some trouble with my short example.
g77 -c binary_fortran.f
g77 -o io binary_fortran.o
./io
11 254 254.
12 253 126.
13 252 84.
14 251 62.
15 250 50.
16 249 41.
17 248 35.
18 247 30.
19 246 27.
20 245 24.
python -i read_fortran.py
>>> a
array([(16, 1090921693195, 254.0), (16, 16,
5.3686493512014268e-312),

(16, 1052266987540, 24.0)],
dtype=[('irow', '<i8'), ('icol', '<i8'), ('value',
'<f8')])
How can I fix the problem ?
