I guess nothing is stopping you from using a datum outside its intended
area, at least when one is talking about geographic coordinates and not
plane coordinates. Do note that Bob's spec has designated datum byte N
to mean NAD27, not 83. I didn't see a byte allocated for NAD83 in Bob's
documentation.
