摘要： A "navigation protocol" is implemented via a computer program to provide communication and invocation capability among object-oriented application programs and precompiled library routines, collectively referred to as `programs`. Each application program is "registered" with the operating environment during its installation; registration entails updating a registration-table data structure with information about 1) a program identifier; 2) an object-type identifier identifying a class of objects; and 3) an action identifier, e.g., a menu entry, identifying an action which the program can perform on objects of the class specified by the object-type identifier. A user can manipulate an object by selecting the object and requesting that a list of all actions performable on the object be displayed, then selecting one of the displayed possible actions. The displayed actions are actually performed by programs as specified in the registration table; the user need not be concerned with knowing which program to invoke. Programs from a variety of different vendors can interact without any one program needing to know about any other program. This modularity uncouples the development process of the user's system from that of the organizations providing the individual development tools and allows the user to upgrade individual programs as desired.
