[ncl-talk] Error creating binary file

[Rick Brownrigg]

Hi Andrew,

How are you opening the file from the fortran side? The docs for
fbindirwrite state that the fortran equivalent is a file opened with
"'form=unformatted, access=direct, recl= ...'.".

If that doesn't help, I'd be happy to take a look at the file if you are
able to send it to me.

Rick
