Subject: A tad of meta-programming needed

I've got the following hash set up and it works fine.  But this took
more typing than programming.

	h = {:name=>$1,  :n_shares=>$2,  :opened_MDY=>$3,  :closed_MDY=>$4,
		:proceeds=>$5,  :cost=> $6,   :gain_Loss=>$7
	      }

So I'd like to get the following to work:

	field_names =%w<Name Shares Opened_MDY Closed_MDY Proceeds Cost
GainLoss>
	h = {}
	(1..field_names.size).each { |i| h[field_names[i]] = eval($ +
i.to_s) }

But concatenating the character "$" with the value of i converted to a
string, followed be evaluating that as a local variable isn't working
as I coded it.  Can it be easily corrected?

Thanks in Advance,
Richard
