Close Command [ File menu (Startup) or File menu (Graphics)]
When exiting ATOMS, closing the graphics window, reading another file or starting a new file, ATOMS tries to determine if you have made any changes in the structure currently in memory; if so, you are asked if you want to save the file.
First, it checks whether the orientation has changed from the Initial Orientation established during calculation. If so, you can save the current orientation as initial rotations. It also checks whether any dialog in the Input1 and Input2 menus have been opened, or whether there has been any change in the status of atoms marked for non-plotting (see Deleting Atoms ).
