## 4 Invoking `psppire`

### 4.1 The graphic user interface

The PSPPIRE graphic user interface for pspp can perform all functionality of the command line interface. In addition it gives an instantaneous view of the data, variables and statistical output.

The graphic user interface can be started by typing `psppire` at a command prompt. Alternatively many systems have a system of interactive menus or buttons from which `psppire` can be started by a series of mouse clicks.

Once the principles of the pspp system are understood, the graphic user interface is designed to be largely intuitive, and for this reason is covered only very briefly by this manual.
