You can maintain large programs by creating a Visual LISP project and optimizing code.
These topics describes how you can maintain large applications containing multiple files by defining the application as a Visual LISP ® project. Aside from defining the components in your application, you can use Visual LISP projects to define compiler options for the application. This chapter describes the various compiler options and the consequences of each, and tells you how to override these options for individual files in a project.
