Subject: changing hash key

I've been looking for a way to change a hash key.  In my code I'm trying
to change the key from a number to a string.  Do I need to convert the
key to a string and put it new value in there or is my code wrong?

Thanks in advance,
Tim


 def numbers
                  @skty = Hash.new(0)
                  @sktynl.each do |key, value|
                    if key <= "39"
                      key = "SKTY"
                      @skty[key] += value # !> instance variable @skty
not initialized
                    elsif key >="40"
                      key = "SKYNY"
                      @skty[key] += value
                    end
