Abstract
A method and system for controlling references to system storage. Milli-code mode provides a flexible technique for overriding storage controls associated with referencing system storage of a data processing system. The storage controls to be overridden are not replaced and therefore, a restore of the previous contents of those controls is not necessary. This allows for an increase in system performance and an increase in the efficiency and flexibility of the system. In addition to the above, a system request instruction is provided, which enables flexibility in the manner in which system requests are executed. The flexibility of the system request instruction reduces the number of instructions needed to perform system requests.
