There is one little question i want to ask. How do convert these two hashes: [{xxxxxx},{yyyyyy}] to be like this: [{xxxxxx, yyyyyy}] Is it possible at all? Regarding the Environmental class. I still need that class because i want to open my yaml file to be used by many subclasses, not just EnergyManagement only. Thanks Nizam -- Posted via http://www.ruby-forum.com/.
