hi,

>v.distance from=txtloc at PERMANENT to=RA at PERMANENT to_type=line,area
upload=cat column=cat to_column=RA_CODE

try to choose another column than "cat",

I've tested with the nc-sample-dataset by
WinGRASS-6.4.SVN-r47802-1-Setup.exe:

g.copy vect=bridges at PERMANENT,mybrigdes
g.copy vect=lakes at PERMANENT,mylakes
v.db.addcol map=mybridges at g7 columns="areacat INT"

v.distance --overwrite --verbose from=mybridges at g7 to=mylakes at g7
to_type=area upload=cat column=areacat 

Helmut
