[Paraview] Writing binary files: C/Fortran interface to VTKXMLfiles.

[SamuelKey]

Stephen;

In this context (Fortran) --

UNFORMATTED => blocked binary with leading and/or trailing word counts
                                     usually compiler dependent.
BINARY ==> Unblocked binary byte stream, typical of C, usually direct
access (if you remember to record where you wrote what).

BINARY is only supported in Fortran as an extension. Compilers that have
this
extension are

1) HP/Compaq/Digital Visual Fortran under Windowsxx Windows XP64,
2) G95 (http://www.g95.org) there called streaming I/O
3) PathScale Fortran-95 under Linux
4) Others

Regards,

Sam Key
