Thanks Phil.

But I would rather prefer the "magic line" fortran code (if it exists) 
to write directly the binary file with the right format.

For instance, as seen on the web,

open(unit=20, file='foo.dat', form='unformatted', access='stream')
does not work:

  Fortran runtime error: Bad ACCESS parameter in OPEN statement

In fact, I would like to know all access parameters for the open 
statement. Where could I get them ?

I did not find relevant info, in gfortran manpage, gfortran info, etc.


Cheers,
