Returns parts of the output of variables .Machine and
.Platform. Endian Problem
these should be used for reading binary data when crossing platforms.
If binary files are created on a little-endian platform, but are being

SizeOf Problem
Many older machines use 4 bytes for LONG. Newer 64 bit machines use 8
bytes for LONG = so this is a big problem.
