thanks for response. I see what you are trying to say, but this line
right here:
s_code << {unit_id => unit_id_hash}
it just creates a hash like this:
{unit_id => {}}
and then latter we insert items into it, always the same way, whether
it's the first time we insert item or not:
unit_id_hash[key] << code if key
So if you see a problem here, maybe I am not understanding.
thanks for response
