    In this paper, we have discussed some of the salient aspects of virtual storage systems. Further, in the discussions of virtual machines and CP-67, we have illustrated an implementation of a virtual storage system as well as the generalization of the virtual storage concept to virtual machines. Although a virtual machine system does not within its strictly defined limits admit to the more complex ... View full abstract»

    The Model 67 with CP-67 was installed at Pratt & Whitney Aircraft to meet specific requirements of their engineering department that could not be met by a traditional batch computer system. An extensive interactive graphics system, using graphic display consoles, has been developed to assist the engineer and reduce the development cycle time of an engineering design. The interactive programmin... View full abstract»

    The machining of three dimensional objects that embody complex surfaces such as aircraft contours or ship propellers challenges the machine tool numerical control programmer. In industries where automated manufacturing is playing an increasingly important role, product designs often call for physical surfaces that cannot be represented analytically by simple mathematical expressions. An aircraft f... View full abstract»

    A general management game has been described that simulates a manufacturing industry environment and is programmed in an interactive conversational mode using APL. The game has proved to be a valuable means of training individuals in decision-making. Further details are given in Reference 7. The game is also used for experimental purposes, and improvements are being made constantly to reflect the ... View full abstract»
