Generating assembly code
.PP
When the code expander generator is used for generating assembly instead of
object code (see section 5), not all the above mentioned constants
and functions have to
be defined. In this
case, the constants ``BYTES_REVERSED'' and ``WORDS_\%REVERSED'' are not used.
object code (see section 5), additional print formats have to be defined
in ``mach.h''. The following table lists these formats.
