Sorry for the missunderstanding: it is not an error message, the programs
run without issuing any error at all. But the result is wrong.
As I indicated in my original message, the problem is most
likely due to an error in the (non-grass) program that projects
lat,lon coordinates into Goode-Homolosine. I can visualize
the wrong node, but cannot find it in the 
ascii vector file to correct it. The problem could be solved if
I could know the exact coordinates of the node, as I could
just search the coordinates with the editor. So, my question,
again, is 

how can I get the exact coordinates of a given node?

As far as I've seen, both d.what.vect and v.digspline give
cursor coordiantes, not node coordinates. 

Thanks for your help
