This book aims to provide an in-depth guide to the new Windows 3 version of Lotus 1-2-3. It focuses on the traditional components of the 1-2-3 spreadsheet program-worksheets, charts, databases, and macros - and on the ways in which these software features can be integrated with other Windows applications. To make this tutorial accessible and useful for a broad range of readers, each major part of the book is divided into clearly identified levels of information: step-by-step procedural chapters for users who are new to 1-2-3 and possibly new to Windows as well; practical business-oriented application chapters for readers who learn best by studying realistic business examples; and advanced chapters for experienced users who are ready to master the more complex features of the software. It also covers linked spreadsheets, three-dimensional charts, desktop publishing of worksheet-based documents, macro programming, and the techniques of data exchange with other Windows 3 applications. This book is written for business-oriented users of 1-2-3, new and experienced alike.
