Fortran unformatted data: Big or little endian [message #34961]

Hello Newsgroup,

I have a problem reading Fortran unformatted data in IDL. I have a file
containing data of well known size (e.g., an array of 100 x 100 single
precision floating point values). Unfortunately, I don't know something
about the machine (big or little endian machine) on which the file has
been produced. Is there a way to get this information on the fly by IDL
in order to open the file automatically in the correctly (using the
/SWAP_ENDIAN option or not). The way I used so far was trial and error.
But since I have many of those files I'm searching for a solution
without recompiling my source code.

Do you have any ideas?

Thanks in advance.

Regards

Michael
