[GRASSLIST:7505] attribute for boundary and arcinfo-coverage

[Helmut Kudrnovsky]

dear grass-friends,

i´ve imported a polygon-shapefile with v.in.ogr. the polygones are 
different types of biotops with a lot of attributes (coloumns) in the 
shape-dbf.

i surfed a little bit through the grass 6.0.x-manual pages, but there are 
still two questions:

is it possible in grass to define the boundary of the polygones between the 
different types of biotops and to give attributes for the boundaries of the 
polygones?

for example:
-the boundary between biotop typ 1 and biotop typ 1 should get the attribute A
-the boundary between biotop typ 1 and biotop typ 2 should get the attribute B

is it possible to export grass-vector-layers to arcinfo-coverages and if 
yes with which precision (single/double)?

with a lot of thanks in advance and greetings from tyrol
