Reading fortran unformatted data

[Chris Picton <chrisp@xxxxxxxxxxxxxxxxxx>]

Hi

Im am trying to read 4-dimensional data from a file written by a fortran
program.

The code which wrote the file looks something like this.

     WRITE (20)
     +       (((DOUT(L,K,IZ,J,I,IP),L=1,NLG),K=NLT,1,-1),IZ=1,NZ)

IP is fixed, and there is a loop over J and I

ie, it writes J*I records (these are incremental in time), and each record
is a block of 3-dimensional data.  This is written as an unformatted
stream.

Is there any way to read this entire data file in ferret?  Any help would
be appreciated

Thanks
