Abstract: An expert system is provided which can be accessed by other application programs operating within any of the available operating environments in a general purpose computer system. In this architecture, an expert system consultation subsystem provides the means for performing expert consultations. Included within the expert system subsystem is a task manager which initiates and manages a plurality of concurrent consultations. Interface programming provides the capability for the expert system consultation subsystem to communicate and pass data and commands between it and other application programs operating within the computer system. Further, means are provided to allow the expert system subsystem to access data stored on database management systems.

Abstract: A data processing system method and program are disclosed for limiting a book reading program for softcopy books, to be capable of reading only softcopy books published by a selected publisher. The method includes the step of generating with a data processor, a customized polynomial expression to be associated with a selected softcopy book publisher. The method continues by merging with a data processor, the customized polynomial expression with a first shell program, forming a stamping tool program for stamping a key value onto a softcopy book published by the selected publisher. The key value results from the polynomial, using the product of an integer times a hash value of the publisher's identity, as the value of the independent variable. Then the method continues by generating with a data processor, a customized inverse polynomial expression to the customized polynomial expression, to be associated with the selected softcopy book publisher. Finally, the method merges with a data processor, the customized inverse polynomial expression with a second shell program, forming a book validation program for validating the key value on the softcopy book published by the selected publisher and enabling a softcopy book reading program to read the softcopy book. If the key value read from the book by the validation program, is determined to be an integral multiple of the publisher's hash value, then the key is valid.
