[GRASS5] v.in.ascii problems

[Michael Barton]

In GRASS 5.7, I¹ve used v.in.ascii in the past to import point files to
vector points. It is supposed to also import ascii vector files and convert
them to binary. I tried it today and it didn¹t work. To test it, I exported
a small vector file to ascii‹using v.out.ascii. I tried it with the ver. 4
flag checked and unchecked (it gave me identical results in this case). Then
I tried to import the same file. Here is the output:

v.in.ascii input=vector_test_ver4 output=vector_test
WARNING: The vector 'vector_test' already exists and will be
overwritten.uilding topology ...
Registering lines: 
1 primitives registered
Building areas:  100%0 areas built
0 isles built
Attaching islands: 
                   
Attaching centroids:  100%
                   
Topology was built.
Number of nodes     :   2
Number of primitives:   1
Number of points    :   0
Number of lines     :   1
Number of boundaries:   0
Number of centroids :   0
Number of areas     :   0
Number of isles     :   0


The line actually has 53 nodes. When I go to display it, there is nothing to
display.

What I am trying to do is convert a track of gps points into a vector line
for display. This should be relatively easy using v.in.ascii. But something
is not working‹or am I missing a subtle point somewhere?
