Exact position of nodes in vector files

I've (succesfuly) imported an arc info vector
file in geographic (lat,lon) coordinates using v.in.arc  

Then I have transformed the ascii vector file from the
original geographic coordinates to Goode-Homolosine
coordinates using a non-Grass program.

Once I import the new ascii vector using v.in.ascii,
there is one single error: one node is very far away 
from the region. This is probably due to some wrong 
character written by the program doing the transformation.

I would need to identify the EXACT coordinates of this
node, then I would be able to search for it in the 
ascii vector file, correct it and run v.in.ascii

Nevertheless, I've tried both v.what and v.digspline
(i'm using grass5.0beta), and I've identified that this
wrong node is node 23 on line 23, but cannot get the
coordinates: I get cursor coordinates, but
not the coordinates of the node.

Is there any way I could identify the EXACT coordinates
of any given node?
