Subject: Re: changing hash key

This is not working because you're using a string called '@acctnum'
instead of the content of the variable @acctnum inside both has_key? and
merge functions

First remove ' signs from that functions, next I suggest you to use
symbols instead
of variables for keys (@acctnum.to_sym instead of @acctnum)

Bye

 sktylist = Hash.new("")
             if sktylist.has_key?('@acctnum')
               sktylist.merge!('@acctnum' => 'value')
 else
               sktylist[@acctnum] = [value]
             end
             sktylist.each { |key, value| puts "#{key} equals #{value}"
}
