Subject: Re: changing hash key

Hmm ok then maybe changing the keys is not what I need to do then.

The reason I have skty and sktyny is that those are account names, sorry 
should have stated that earlier.  So I have a list of account numbers 
and their balances, all accounts listed 500 through 539 should have a 
key of skty and accounts with 540 through 550 should be sktyny.  All the 
account balances for skty should be combined into the value for skty 
and all the balances should be combined for teh value of sktyny.  Here 
is the full code, I did not want to post  a mile long request with it 
all in there.

          value = lv.to_f/100
          value = -value if is_negative

          # Add vales to hash
