Getting out the coordinates

  We have a vector file, that consists of basin boundaries,
This file was converted to a vector file from a raster map. When I took
a v.out.ascii of the file I got one area that had only two points as shown below
  A 2
39.20390923 -106.49873727
39.22168803 -106.49873727
A 3
39.24391153 -106.18987383
39.18835278 -106.18987383
39.18835278 -106.19209587

my question is how can an area have two points and then how can I get
an ascii file that has coordinates of all the points of a given area.

it is not an area, but an area-edge.

The `A 2' means `Now follows an >AREA< edge of 2 coordinates'. So the two
points do not describe an area, just one of its edges.
