LAYOUT CONVENTIONS

To keep this book as clear and easy to follow as possible, the following text conventions are used throughout.

• Important words or concepts are normally highlighted on the first appearance in bold type.
• Code is presented in fixed-width font.
• New or changed code is normally presented in bold fixed-width font.
• Pseudo-code and variable input are written in italic fixed-width font.
• Menu commands are written in the form Menu Submenu Submenu.
• Where we want to draw your attention to something, we've highlighted it like this:

  Ahem, don't say we didn't warn you.

• Sometimes code won't fit on a single line in a book. Where this happens, we use an arrow like this:
  This is a very, very long section of code that should be written all on
the same line without a break.
