@ -1221,6 +1221,14 @@ code fragment) by using \c{[byte eax+offset]}. As special cases,
\c{[dword eax]} will code it with a double-word offset of zero. The
normal form, \c{[eax]}, will be coded with no offset field.
The form described in the previous paragraph is also useful if you
are trying to access data in a 32-bit segment from within 16 bit code.
For more information on this see the section on mixed-size addressing
(\k{mixaddr}). In particular, if you need to access data with a known
offset that is larger than will fit in a 16-bit value, if you don't
specify that it is a dword offset, nasm will cause the high word of
the offset to be lost.
Similarly, NASM will split \c{[eax*2]} into \c{[eax+eax]} because
that allows the offset field to be absent and space to be saved; in
fact, it will also split \c{[eax*2+offset]} into
