In System Architect, symbols can be addressed by one or more (addressable) definitions. Fifteen addressable definitions are automatically supplied and they can be addressed to any symbol: Business Objectives, Business Process, Change Requests, Critical Success Factor, Current Data Collection, Data Class, Deliverable, Functional Organization, Geographic Location, Information Requirement, Organization Goals, Requirements, Test Plans, Issue, and Risk. These addressable definitions are available by selecting a symbol on a diagram, and choosing Dictionary, Addresses. In addition, any definition can be declared addressable through the syntax in USRPROPS.TXT. Doing so makes the definition available to address a symbol, and places it on the Dictionary, Addresses drop-down list.
