“…Form of the utility Yucca-* is designed to be an external utility, rather than an integral system component such as are Cousin (Hayes, 1982b), (Hayes, 1982a), (Hayes and Szekely, 1983), SARA (Fenschel and Estrin, 1982), and CONSUL (Mark et al, 1980). This means that it must run as a separate program on the existing system, to be invoked only when needed.…”

Abstract. Yucca-* is a consultation system which is designed to provide the UNIX user, through a friendly interface, with detailed expert advice on the use of the UNIX command language. One of the principal design goals of this system is the ability to provide correct responses to technically complex queries whose solution may involve the interconnection of several commands, each with multiple options. The realization of such a goal requires two things. First, representation of dynamic knowledge about command behavior at a sufficient level of detail to support solution of the query is needed. Second, a planning mechanism capable of interconnecting such knowledge into a cohesive solution must be provided. This paper first develops the command dynamics representation techniques employed in Yucca-*. It then examines in detail the plan generation mechanism which is used to solve complex dynamic queries. Particular emphasis is placed upon those aspects of the problem which are unique to this particular domain.

“…Dominating the literature are technical approaches to provide , sophisticated help interfaces to users. Examples of these efforts are the context-sensitive help interfaces developed by Fenchel and Estrin (1982), adaptive command-prompting interfaces N (Mason, 1986), help systems that provide concrete simulations relevant to the user's task I' (Grignetti, et al, 1975), help interfaces with natural language front-ends (Wilensky, et al, -s .…”

“…The language specification must be written in a well-structured manner using descriptive nonterminals in order to provide the best assistance. The grammar is analyzed to determine a "covering " (descriptive) nonterminal for each input accepting state [32]. The covering nonterminals serve as a characterization of expected inputs for each state of a parse and also as a handle for retrieving additional detail from the help database.…”

“…Certain states can accept optional inputs and are therefore described by simple covering nonterminals, each describing an option. By following a small number of naming conventions and abstraction rules, SARA tool designers are able to specify context free grammars well-suited for this description method [32], [33].…”

An environment to support designers in the modeling, analysis, and simulation of concurrent systems is described. It is shown how a fully nested structure model supports multilevel design and focuses attention on the interfaces between the modules which serve to encapsulate behavior. Using simple examples the paper indicates how a formal graph model can be used to model behavior in three domains: control flow, data flow, and interpretation. The effectiveness of the explicit environment model in SARA is discussed and the capability to analyze correctness and evaluate performance of a system model are demonstrated. A description of the integral help designed into SARA shows how the designer can be offered consistent use of any new tool introduced to support the design process.
