wxCLIPS has a basic development environment, consisting of a window with menus, a small input window, and an output text window.
Type into the text input window and press the Go button to send the input to CLIPS. Results and error messages are written to the output window. Don't expect to use standard input in your CLIPS programs, since the text window is read-only, and when your program finally runs it will probably have its own specialised interface for entering and displaying data.
The menu bar contains menus for loading and saving CLIPS files, and substitutes for various CLIPS functions, such as clearing and starting the rule interpreter and listing CLIPS constructs.
