The Window
The picture below shows the window when starting QtOctave.

There are five tools shown: Variable list, Command List, Navigator, Terminal and Editor. To begin with, you will only need the terminal. The terminal is used when writing commands on one line. If you want to write commands on several lines, you do it using the editor-tool. The commands written in the editor are then saved in so called M-files.
