Determining machine endian-ness [message #12161]

Is there a way to determine whether the machine on which IDL is executing is
big endian or little endian? I am trying to read a data file which I know
contains little-endian data. I need to byte swap this data if IDL is running
on a big-endian machine, but not byte-swap if it is running on a little-endian
machine.

It would be nice there were a field in !VERSION which contained this
information. Right now I am testing if !VERSION.ARCH eq 'x26', 'alpha', etc.
There must be a better way.
