MacPac Numbering 2000 includes three kinds of schemes available for users - Public, Private and Document Schemes. Public Schemes are a firm or organization's standard schemes and are maintained by the system administrator.

Because individual users cannot directly edit the Public Schemes, the standard schemes for the organization remain constant and always available. Users can however, use a Public Scheme as the blueprint for creating a Private or Document Scheme.

The Numbering Schemes Dialog lists and displays a preview of all available Public and Private Schemes. The dialog also includes Scheme and Share menus for working with and sharing the numbering schemes.
