2.8 Summary

In this introductory tutorial you have seen how to perform the following actions:

• Start the windowing environment.
• Evaluate and re-evaluate Common Lisp forms using the Listener.
• Invoke the Debugger, follow the backtrace that it produces, and return from the error which caused entry to the Debugger.
• Collect and display data generated by your own code in the Output Browser.
• Use the Inspector to examine the current state of an object.
• Use the Class Browser to find out detailed information about a given class, so that you can make arbitrary programmatic changes to an instance of that class.

The next two chapters describe elements of the environment which are common to all tools.

Other chapters in this manual describe the other tools available in the environment. Each chapter is intended to be reasonably independent of the others, so you can look at them in any order you wish. You are advised to study the chapters on the basic tools, such as the Inspector, the Class Browser and the Editor first, since a knowledge of these tools is vital if you want to get the best out of the environment.
