I believe the examples on p. 67 of the PDF version of the 3rd edition of
the NACO Participants' Manual have incorrect coding--see
This page is about optional 781 Subdivision Linking Entry for Geographic
Subdivision. The instructions say to use $z but the examples have the
initial subfield coded $a. I checked DCM Z1 and the examples there use $z.
Can these examples be corrected in the PDF version?
