EBook structure

The first thing you need to know to use the entire power of the compiler is how an eBook works.

When the eBook application is running, the user works in a visual environment consisting of four visual areas: Control Bar, Search Bar, Main Panel and Left Panel. Each eBook contains six virtual file directories: Control Bar Directory, Search Bar Directory, Buy Page Directory, eBook Directory, Left Panel Subdirectory and Protected Subdirectory. End users work only with visual areas and they do not even suspect that there are some directories, but the visual areas depend directly on the file directories. Each visual area shows pages only from those file directories that are associated with it. The Control Bar shows pages from the Control Bar Directory; the Search Bar - from the Search Bar Directory; the Main Panel - from the Buy Page Directory, eBook Directory and Protected Sub Directory; the Left Panel - from the Left Panel Sub Directory.

The structure of the eBook can be shown with the help of the following scheme:

Gray rectangles are visual areas, green rectangles are file directories and the arrows from the green rectangles to the gray ones show where the pages are displayed.
