Subject: Problem with v.category

Platform: GNU/Linux/i386
grass obtained from: CVS
grass binary for platform: Downloaded precompiled Binaries
GRASS Version: grass5.7.cvs-i686-pc-linux-gnu-23_10_200


I need to change the category value of several areas in order to query a DB,
and v.category is not working fine.


- I'm running version grass5.7.cvs-i686-pc-linux-gnu-23_10_2004, and I need to
change de category value of an area.
If  I run this
v.category input="vec_area_3" output="vec_Area_34" type="boundary,centroid,area"
option="add" cat=4 field=1 step=1

only the value of boundary change, the value of Area is still 1

If I run this
v.category input="vec_area_3" output="vec_Area_34" type="area" option="add" cat=4
field=1 step=1
the value of area is still 1, nothing change

- I changed the version to grass5.7.cvs-i686-pc-linux-gnu-06_11_2004
and if i run 
v.category input="vec_area_3" output="vec_Area_34" type="boundary,centroid,area"
option="add" cat=4 field=1 step=1

the vector vac_area_34 is not createad, nothing happen.

v.category option=add can add a new category to elements without
category. You need v.reclass or v.category option=del + v.category 
option=add

I solve the problem with the following commnad,

example to assing cat=3 to the first field

v.category input=dbCScr1_areas0 output=catdbCScr1_areas0 type=area option=sum
cat=3 field=1 step=3

I don't really know if this is correct, but work fine !

thanks for your reply,
and I´m sorry for my late response
