The content and format of the output can be controlled using the Options | Output Control menu item. The properties to be displayed in the output can be selected. If the desired display units for a property differ for a property, the new units can be specified in the output control window. A specific output configuration can be set to be the default configuration used every time SteamCalc is started. In addition, multiple output configurations can be saved to a file and recalled at a later time using the Save/Load Preferences buttons.
