Conventions Used in This Book The following is a list of the typographical conventions used in this book:Italics Used for emphasis, new terms where they are defined, and URLs. Constant width Used to show code examples, the contents of files, console output, and the names of variables, commands, and other code excerpts. Also used for VBA macro and module names.
Constant width bold Used to highlight portions of code (typically new additions to old code) and to indicate text that should be typed literally by the user. Constant width italic Used in code examples and tables to show sample text that should be replaced with user-supplied values.
_ Underscores are the line-continuation characters in the VBA language. An underscore at the end of a line of VBA code indicates that the statement continues to the next line. These line breaks have been added to fit the text to the width of a page, as well as to aid in readability. They are optional, but if used, must be the final character on a line and must be preceded by a space. Word treats two (or more) lines of code separated by such an underscore as a single line of code.
Used to indicate an optional line break inserted within a field code. To insert a line break within Word, type Shift-Enter. The character doesn't display on screen unless you've checked the box marked Paragraph Marks under Tools Options View.
