1. An apparatus for providing an expert systems toolkit, comprising:

  • a memory for storing data;

    a computer coupled to said memory and having a video display and an input device;

    a program in execution by said computer for controlling operations thereof for receiving user input defining one or more analysis rules to be applied to user specified data from said memory, each said analysis rule being a user defined arithmetic and/or logic test to be applied to user specified items of said data and for controlling said computer to receive and store user entered data defining the alphanumeric text of a diagnostic statement associated with each true result of each said analysis rule, each said diagnostic statement comprised of a user defined alphanumeric text string which the user can program to define the significance of the true result, its relevance or any other expression which provides meaning to the user of the true result of the analysis rule, and for controlling said computer to receive user input controlling which of said analysis rules are to be applied to said data, and for applying said analysis rules so designated to the data designated by said user and returning a true or false result for each analysis rule so applied depending upon the state of the data to which each analysis rule was applied, and for each true result returned by an analysis rule, controlling said computer to store in a file in said memory the user programmed text of a diagnostic statement associated with each true result as a diagnostic in a diagnostic database, and for controlling said computer to receive and store in said memory user input defining one or more expert tests, each expert test comprising a user defined arithmetic and/or logic statement to be applied to one or more diagnostics selected by user input from the diagnostics stored in said diagnostic database, said arithmetic and/or logic statement comprised of mathematical operators and/or logical operators from any logic set such as predicate logic or Boolean logic including at least the AND, OR and NOT functions, each said expert test returning either a true or false result, and for controlling said computer to receive user input defining the text of a super diagnostic statement in the form of an alphanumeric string associated with each true result of one of said expert tests, each said superdiagnostic being an alphanumeric string which the user can program to define the significance of the true result of the expert rule, its relevance or any other expression which provides meaning to the user of the true result of the expert rule, and for controlling said computer to receive user input defining which of said expert tests to execute on user specified diagnostics in said diagnostic database, and for controlling the computer to execute the expert tests so designated, and for controlling said computer to store as a super diagnostic in a super diagnostic file in said memory the super diagnostic statement associated with any true result returned by any said expert test.
