Here is an article on the subject, with a little snippet
of code to tell you where you are.

http://www.dfanning.com/tips/endian_machines.html

The code looks like this:

little_endian = (BYTE(1, 0, 1))[0]
IF (little_endian) THEN $
Print, "I'm little endian." ELSE $
Print, "I'm big endian."

Cheers,

David
