  • Publication number: 20040154007
    Abstract: A translator system for translating source programs into machine language programs in an electronic computer system. An object program common to a plurality of different machine types of computers are generated while implementing execution performance equivalent to object programs inherent to the computers. A compiler translates a source program into an abstract object program including an abstract machine instruction sequence and indication concerning allocation of abstract registers. An installer converts the abstract object program into a machine language program of target computer on the basis of executable computer specification information including register usage indication and machine instruction selecting rules.

  • Patent number: 6061516
    Abstract: An online application processing system capable of carrying out online application processing through the use of an easy-to-operate GUI environment takes advantage of the fact that the types of data exchanged by online application programs with a host terminal have conventionally been determined by the specifications of the terminal and are thus common to numerous online application programs. By matching data formats so that existing online application programs are used without modification, a GUI processing program is used as a host access program.

  • Patent number: 5504676
    Abstract: A slip processing method for simplifying a processing of a job which uses a form of a predetermined format at a frequency of once a long term such as month, quarter or year and in which an input form is changed at a frequency of once per several times of use. The method comprises storing format information of an input form and data information in one file, providing a format of the input form including a plurality of tables each comprising a plurality of items (cells), storing data in corresponding ones of the items, executing a retrieval of the items and a totalization of data in the items with referencing a file which stores the format information and the data of the input form and storing the format information and the data of the input form and the processed information in a form which is transmittable through a network.

  • Patent number: 5465299
    Abstract: In a terminal which received an electronic document with at leastone digital signature, when a user changes the contents of the received electronic document, a new digital signature is produced by enciphering signature data by using a secret key of the user, the signature data including a hash total of the document of a new version, personal information of the user (signatory), and version management information necessary to restore an electronic document of a former version from the electronic document of the new version. The new digital signature and the new version electronic document version are transmitted together with the received digital signature to a next person on a document circulating route.

  • Patent number: 5414864
    Abstract: In a data processing system having a central processing unit including a register file for storage of often-used data, a method and system is provided for saving and restoring the contents of the register file from the main memory only when necessary. Each register unit in the register file includes a register protection flag, a save area pointer and a plurality of general purpose registers. The register protection flag is coded to identify if the register unit is in actual use by having contents stored in any of the general purpose registers. Before saving or restoring the register unit, its register protection flag is checked, and only if the flag indicates actual use is the saving or restoring performed.
