I suspect it works *most* of the time. I don't see anything
in there to *cause* the error. :-)

You can certainly read data any way you like. It's not
until you try to make *sense* of the data that you are
likely to run into trouble. In your case, you might try
reading a known data value from the file. It that value
is total nonsense (your were expecting 45 and you get
-20435), then you could "throw" an error, rewind the file,
and read the data again with the SWAP_ENDIAN keyword set.

Cheers,

David
