wxCLIPS has a basic development environment, consisting of a window with menus, a small input window, an output text window, and a toolbar (Windows only).
Type into the text input window and press return or 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.
Under Windows, there is a toolbar to accelerate a few commonly-used commands such as loading, batching, running the rule system and running a GUI application. Depending on platform, you may also be able to copy a command from the development window and paste into the command line; under Windows, select the text with the mouse, then press the Copy tool, click on the command line, and press shift-insert.
There is no in situ editing of CLIPS files, but see DDE commands that wxCLIPS recognizes, which shows how some integration with an editor is now possible.
