Subject: setting instance variable "dynamically"

I saw in the pickaxe there's a way to call methods dynamically, with
send("method_name"):

"test".send("length")  # 4

What I want to do is set a variable this way. Is it possible?

I'm working on a translation tool for a website. rows returned
are of the form:
["id", "language", "value"]

the value of the language field is the identical to the member variable
that will contain the row (wrapped in an object actually).

I thought of something like this:

class Term
attr :query, :fr, :nl, :en
     def initialize(dbh, id)
         @query = "select * from translations where id='#{id}'"
         dbh.select_all(query) do |row|
             self.send(row[1].to_s)=Translation.new(row)
         end
     end
     def get_french()
         @fr.value
     end
end

But that isn't accepted.
Does anyone have the solution?

Thanks
