- Add to the list CRAY (see below).

- This is correct for the CRAY too, you need the OS to do 64 bit to 32 bit
- translation.

- Not so for the CRAY.

-
- Yes (see above), but you need to either read them with a C program, or
- use direct access. For an answer to this question, see my previous
- posting.
