Conventions Used in This Book

Throughout this book, we've used the following typographic conventions:

Constant width

Constant width in body text indicates an HTML tag or attribute, a scripting language construct (like For or Set), an intrinsic or user-defined constant, or an expression (like dElapTime = Timer( )-dStartTime). Code fragments and code examples appear exclusively in constant-width text. In syntax statements and prototypes, text in constant width indicates such language elements as the method or property name and any invariable elements required by the syntax. Constant width is also used for operators, statements, and code fragments.

Constant width italic

Constant width italic in body text indicates parameter and variable names. In syntax statements or prototypes, constant width italic indicates replaceable parameters.

Italic

Italicized words in the text indicate intrinsic or user-defined functions and procedure names. Many system elements, such as paths, filenames, and URLs, are also italicized. Finally, italic is used to denote a term that's used for the first time.

This symbol indicates a tip.

This symbol indicates a warning.
