Why not? Of course you also have to write the data using /XDR.
This is the easiest way to keep code *and* data platform-independent.

You're mixing things up. Little Endian is a *hardware* thing. It has
nothing to do with the OS you are running. IDL for Linux is still LE.
We have a mixed cluster here (SunOS, HP-UX, Linux), all Unix. Still
there is the Big/Little Endian problem.
