Subject: Question on saving variables

I run into the following situation: I have to pre-process some data and
then use varaibles to represent these processed data. I also want to 
use these variables in many places but I do not want to turn all of them
into class instance variables. (@variable, that is) and I don't want to 
pass them as parameters for the method ( so I could use anything I want
without changing the method declaration)
 
What are the alternatives?

Thanks.

RubyQ.

Example:

class Something

def initialize(v1, v2, data)
    # blah, blah, blah
end

def act(data)
    #preprocess the data 
    #d1, d2, d3 and so on is available now

end

def use1()
    #use some of the d's ( it can be d2, d7 )
end

def use2()
    #use some of the d's (it can be d1, d4 )

end

def use3()
    # and so on....
end


end
