Yes. And I am not trying to be a wise guy here, but don't
pass BYTEORDER strings.
What do you imagine would be the proper thing to do with
a string? What would it mean to swap the byte order of
a string, which is, in essence, a sequence of bytes? You
certainly wouldn't want to *reverse* the string, unless you
planned to read the string in a mirror.
If you look at a routine like SWAP_ENDIAN in IDL, which
*does* accept strings as arguments, you will see that
it simply returns the strings it receives as arguments
without changing a thing. This is exactly as it should
be.
Cheers,
David
