Byte Order 

The VAX computer has a different byte order from HP 9000 computers.
Binary data files created on a VAX computer may need to be swapped before
they can be interpreted on an HP 9000 Series 700/800 computer.  Use the
descriptions of storage and alignment on both systems to write a
programming tool to reorder the data.  The C library function swab (see
the HP-UX Reference Manual) can be used to swap bytes, if that is
sufficient for the particular application.  Otherwise, you need to write
a customized tool.  ASCII code and data files should migrate to the HP
9000 Series 700/800 without change.
