Abstract: PURPOSE: To block undesired access to an address space by performing the user management of address space corresponding to a token applied from a system for space identification. CONSTITUTION: An access register transform(ART) operation 10 uses contents in an access register for providing a segment table describer(STD) to be used for dynamic address translation(DAT). An instruction 12 contains an OP code, B field for designating a general-purpose register 14 containing a base address, and displacement D for generating the logical address of a storage area operand while being combined with the base address in the general-purpose register 14 through an adder 15. The STD from the ART 10 is combined with the logical address from the adder 15 and translated together by a DAT 18, and the real address of an operand to be used for the system is generated.

Abstract: PURPOSE: To make permission hierarchical and non-hierarchical as well by providing a program permitting mechanism equipped with plural access registers and an access register transformation(ART) means. CONSTITUTION: An instruction 12 contains an OP code, B field for designating a general-purpose register 14 containing a base address, and displacement D for generating the logical address of a storage area operand while being combined with the base address in the general-purpose register 14 through an adder 15. An ART operation 10 uses contents in access registers 16 for providing a segment table describer (STD) to be used for dynamic address translation(DAT). When an access list entry token (AELT) is transformed by the ART 10, the STD corresponding to an address space for storing data is applied. The real address of an operand to be used for a system is generated from DAT 18.

Abstract: PURPOSE: To realize a message processing system independent of language to be used which is used with an applicable work by combining information from a file corresponding to a prescribed message with information supplied from the applicable work, and generating a message by a message processor. CONSTITUTION: Message storages 14, 16, and 18 are set in a file to which access can be performed from a message processor 12, and different storage is set for each supported language. When an applicable work 10 calls the message processor 12, and transfers variable information included in a message, the message processor 12 fetches a message syntax and a fixed field from the appropriate storage, assembles and generates the messages by using the information from the storage and information presented by the calling applicable task. Thus, it is possible to realize a message processing system independent of the language to be used for the display of the message, which is used with the computer applicable task.

Abstract: PURPOSE: To control the number of users given access by forming a list of permitted users, and returning access permission to a requesting side only in the case where the list is scanned within the range of a depth parameter, and an identifier matches. CONSTITUTION: A CPU 1 contains application which is connected to terminals 17 to 23 through buses 9 to 15, and which can be executed in communication relation with one terminal on a down-load interface for a work station being accessed through the designated bus. The CPU 1 forms the list of the permitted users, and encodes the depth parameter N as the key of a CPU identifier and the function of an offset. In response to an application software request from the work station or the user, the list is accessed, and depth N is decoded by the key. Then, the list is scanned within the range of the depth N, and only when the identifier matches, the access permission is given to the requesting side.

Abstract: PURPOSE: To individually control the capability of a user and the acknowledgement right to access a space by providing an access register which includes an access list entry token and operating the token. CONSTITUTION: The token included in the access register 22 specifies a space indirectly, so a nonprivileged instruction or subroutine can save and use the contents of the register 22 for another purpose and restores the contents. Therefore, the control and acknowledgement right of the address space can be corrected by operating the token. Further, the definitions of the address space of a system are given from a 2nd table and central control is therefore enabled. Many users have access lists and are then able to access the address space, and >=2 entries can indicate the same 2nd entry. Consequently, the capability of a user and the acknowledgement right to address the space can separately be controlled.
