The career decision making paradigm underlying the Information System for Vocational Development (ISVD) is briefly stated; it reflects the fact that a person has different information needs associated with different life stages, and with decision making stages within any given life stage. The greater portion of the report deals with the attempts, in Phase I and Phase II of the ISVD project, to make an interactive system which reflects this paradigm. Multiple avenues of access to the four major data files already developed are explained and sample interactions presented. Access routines, or scripts, are defined as programmed structures for interaction between an inquirer (user of the system) and the data files. (TL)
