Abstract
A digital computer system having a memory system organized into procedure and data objects, each having a unique identifier code and an access control list, for storing items of information and a processor for processing data in response to instructions. The instructions contain operation codes and names representing data. Each name corresponds to a name table entry in a name table which contains information from which the processor determines the location and the format for the data. The name table entry specifies a base address of one of a set thereof which change value only when a call or a return instruction is executed. A name interpretation system fetches a name table entry, calculates the base address and a displacement using the name table entry and the current architectural base address and adds the base address to the displacement to form the address of the data represented by the name.
