The online documentation of VB/VBA language components seems to follow the 80/20 rule: the basic facts that you need to use a language statement are provided in the documentation. But the additional 20 percent that you need to use it effectively or to apply it to special cases is conspicuously absent. To a professional VB/VBA programmer, though, this missing 20 percent of the language's documentation isn't a luxury, it's a necessity. And in VB & VBA in a Nutshell: The Language, it finally is available. The bulk of the book consists of an alphabetical reference to the statements, procedures, and functions of the VB/VBA language. Each entry has a standardized listing containing the following information: Its syntax, using standard code conventions Differences in the operation of the keyword in a macro environment (e.g., in Office) and in Visual Basic, if there are any A list of arguments accepted by the function or procedure, if any A description of the data type and the data returned by a function An extended discussion of the keyword that focuses on some of the finer points of its usage that are often omitted from or blurred over by the documentation Tips and gotchas that focus on undocumented behaviors and practical applications for particular language elements.
