"MOP is a subset of DDCMP..."
(p 4-14 of the VAX/VMS Networking Manual)
"DDCMP was designed in 1974 specifically for the Digital Network
Architecture."
(p 28 of pamphlet "Digital's Networks: An Architecture with a Future")

So we are in agreement that LAT-speaking DECservers speak MOP, but
we disagree on whether MOP is part of DNA or not. Fine.

Point taken.
