21.7 Creating a system

If you have followed this example from the beginning, the interface and its callbacks are now completely specified. Next, you can create a Common Lisp system which integrates the interface definition with the callback code.

1. Choose File > New or click . This creates a new, unnamed file in the editor.
2. Type the following form into this new file:

(defsystem ib-test

  (:package "CL-USER")

  :members ("ib-callbacks" "ib-example"))

This form creates a system called ib-test that contains two members; ib-example.lisp (the file containing the interface definition) and ib-callbacks.lisp (the file containing the callback code).

3. Choose File > Save or click to save the new file. Save it in the same directory that you saved the ib-example.lisp and ib-callbacks.lisp files, and call this file defsys.lisp.
