NetBSD/usr.bin/tip/cu.c
cgd 88caf985e6 replace old zzhack structure (YUCK!) and number(), boolean(), character(),
and address() macros with new macros of the same names (to get values),
and macros with those names but with "set" prepended and which take a
second argument (to set values).  The new macros use type casts to do
type conversion, which is much cleaner than using a union and making
endianness-related hacks to get the right 'short's and 'char's from
the right array indices.  (YUCK! again, for good measure.)
