Abstract
A method and system for providing a PROGRAM CALL to a dispatchable unit's base space is described herein. A program call to a dispatchable unit's (PC to DU) base space bit is added to each entry-table entry in order to determine whether a PROGRAM CALL to a base space is to be made. Should the bit indicate that a PROGRAM CALL to a dispatchable unit's base space is to be made, then in one embodiment, the base address space number-second-table entry origin (BASTEO) and base address space number (BASN) stored in the dispatchable unit control table (DUCT) are used in identifying the base space and accessing associated control information for the identified base space. In another embodiment, the BASN stored in the DUCT is used in ASN translation to identify the base space and access the associated control information for the base space.
