Here you see the main screen of Chaos Assembler 3. What always will be visible is the main menu bar at the top of the screen as also the toolbars beneath that. These are the key features of CA3. With these two items you can go everywhere in the program. As you might notice, there's a window inside the main window. That's what we call a child. Automatically the main window will be called the parent.
The child window you see here is the child window you will use the most. In the child you see, you are going to edit your source. This child (further referred to as 'the edit child') has really neat options build in to assist you as a programmer. More about this edit child in the next chapter.
The main menu and the toolbars are very related to each other. The most often used items in the main menu you find back at the toolbars. The first one e.g. is a little blank white paper. When you click on that button, a new source file will be generated and immediately an edit child will appear.
You can open as many child windows as you like. There are more windows of this kind in CA3. The image viewer and the sprite editor e.g. have the same characteristics as the edit child.
