2.1 Developing the program

The program we use in the example is essentially this:

(in-package "CL-USER")
 
(defun hello-world ()
  (capi:display-message "Hello World!"))

with a couple of small modifications which are not important here.

Perform these steps to "develop" the program:

1. Open the source file in the LispWorks Editor tool by evaluating this form:

   (example-edit-file "delivery/hello/hello")
   

2. Compile the program in the LispWorks Editor by the menu command Buffers > Compile.
3. Test the program by calling (hello-world).
