pure binary files in fortran on RS6000 (xlf)

[Francois Normant]

I'm trying to write pure binary files in fortran in order to read them in C.

On CRAY 2, I usually open an unformatted file
	open(unit=70,status='new',form='unformatted',file='foo.out')
and call the setpure function to avoid any control characters
	call setpure(70)

The question is: 

Is there a function equivalent to setpure in xlf (RS6000 fortran) ?

Thanks
