v.db.rim questions

Hello grass growers,

  I posted the following questions to grassu-list a couple of
days ago. Since none of the users has replied, thought the programmers'
list might help. Here are the questions:

  1. Here's my little problem:
     I have a simple database with the following fields:
           name type
           ==============
    label int
          volume int
  and other fields. What I'd like to do is, to set volume to some
  value, say, 100 for all records with label = 5.

  In the command line version, we can do this by making a query and
  using the change command (with -l switch). Is there a way of
  doing the same thing in the menu (interactive) version?

  2. When I am using the cmd version, I can read attributes
  from a vector map by using the .read_vect command with
  a field name, e.g.,
    .read_vect vector_map label <Enter>
  It appears to me that we can't do this in the interactive version.
  Is this true?

  Thanks in advance,
