<div>The problem with binary is that someone must describe how the data was written. Fortran's default (sequential) binary has **hidden record separators**. The user could also open a binary with "access=direct". This means 'flat' binary files (no record separators.<br>

Likely, fbindirread *or* fbinrecread would work. However, without more knowledge not much more can be said.<br>

One major reason for the creation of HDF and netCDF to allow the files to be 'blindly' examined via a suite of standard function functions.<br>

<div>I understand that this is a binary file, so visualization and reading it is much more complicated than it would be with netCDF’s. </div>

<div>Specifically, I have these questions:</div>
<ol>
<li>Will the fbindirread work to read in a .ieeer8 file (I am assuming the file is fortran as it is a restart file for CESM1’s POP2)?</li><li>How do I know what data is stored on the file prior to reading it in (i.e. Variables)? Or is this even possible?</li></ol>
<div>Any help would be greatly appreciated with this, and I am happy to provide more information if it is required.</div>
</div>

<div>Thanks,</div>
