To create a new class you need to open a System Browser, which is in the Browsers menu in the Launcher -- the first window with icons on it.

The leftmost pane of the System Browser is a list of categories. Each category contains related classes. Create a new category (use your project name as a good default) by clicking the middle button in that pane, choosing Add, and typing the name you've chosen in the prompter window.

The category will be added to the category list, and a template for defining a new class has appeared. Now, create your class by:

• Changing the NameOfSuperclass to the name of the superclass (e.g., Object)
• Changing the NameOfClass to the name of your class (e.g., Muppet or MyCoolClass.) Be sure to capitalize the class.
• Change the instance variable list to whatever variables you need (e.g., 'name quantity'). SINGLE quotes are important.
• Typically, change the class variable list to ''. You rarely need class variables.
