Subject: Re: Question on saving variables


Would an array do what you want?

def act(data)
    # Creates the array 'd'
    # d[0], d[1] and so on is available now
end

def use1()
    #use some of the d's ( it can be d[2], d[7] )
end

I think that you do have to use the instance '@d'.  'd' Is local to the
current method (if I understand Ruby scope correctly).

Hope that helps.
