This manual uses a meta-language to describe the ACUCOBOL-GT syntax. This meta-language follows the conventions used in most COBOL manuals as well as the ANSI standard. These conventions are described below.

Unless otherwise indicated, the references to Windows in this manual denote the following 32-bit versions of the Windows operating systems: Windows Vista, Windows XP, Windows NT 4.0 or later, Windows 2000, Windows 2003; and the following 64-bit versions of the Windows operating system: Windows Server 2003 x64, Vista x64. In those instances where it is necessary to make a distinction among the individual versions of those operating systems, we refer to them by their specific version numbers (such as Windows 2000 and Windows NT 4.0).
