I did this in two steps, rather than echoing the data file because it and
where grass runs are two different directories.

analysis_points.dat:

VERTI:
B 5			# There are 5 coordinates and no categories
  -123.940000 45.150100
  -123.940000 45.145400
  -123.960000 45.150100
  -123.960000 45.145400
  -123.940000 45.150100
  1 1
C 1
  -123.950000 45.147500
  1 1

GRASS now fails to import the data file:

v.in.ascii in=analysis_points.dat out=analysis_corners for=standard --o
WARNING: Error reading ASCII file: (unknown type) [ 1 1]
ERROR: Import failed

Grass seems to not like the layer and category number for the centroid as
removing those for the boundary produces the same error.

What am I still missing?

Regards,

Rich
