  • Patent number: 5179698
    Abstract: A computer system for processing complex information representative of business transactions. Specifically, the system stores transaction data, which is then reversibly transformed in accordance with predetermined processing algorithms, while it is externally inaccessible. In this static state, the transformed transaction data is evaluated against predetermined logical criteria. The evaluation produces either successful or unsuccessful results. If successful, the transformed data is then made externally accessible. If unsuccessful, the original transaction data is made externally accessible.

  • Patent number: 4320451
    Abstract: A generalized event management architecture based upon an analysis of the traditional interprocess communication and synchronization mechanisms is disclosed. An extended semaphore architecture is proposed which combines the properties of Dijkstra's semaphore with that of a trap facility. This model is further developed into a more general architecture capable of handling complex events, structured event condition variables and generalized assignments. The architecture is defined in terms of entity classes, relationship classes and functional primitives. Finally a typical hardware computer system utilizing these concepts is shown and described.

  • Patent number: 4068299
    Abstract: An apparatus for utilizing a logical compare instruction is disclosed. The apparatus develops a data field descriptor associated with and describing the attributes of each of the operands of the compare instruction. If the operands have different formats, when matching the contents of a first operand to the contents of a second operand, one operand is converted at execution time of the compare instruction to a format consistent with the other operand. The apparatus determines whether the contents of the first operand is greater than, less than, or equal to the second operand.

  • Patent number: 4068300
    Abstract: A data field descriptor extends the flexibility of operand accesses by defining the attributes of a data field with regard to length, location and form of data representation at execution time. This delay of binding the operand accesses until execution time supports both data independence and security by permitting programs to be compiled without any restrictions imposed by the attributes of data fields. At execution time the necessary information is provided through a register so that the data field information may be correctly processed. With this feature a program is permitted to survive the change in formats of its input and output files without repeatedly undergoing the expensive operation of compilation. Also permitted is processing of files containing data field values which are not uniformly formatted throughout the file but which are self-defining through a data field descriptor.
