  • Stein, D, M, (Computer Society of South Africa (on behalf of SAICSIT), 1980-03-01)
    In this paper some specifics and some generalities on the subject of memory organization for future large processors are discussed. We briefly review the current hierarchy and discuss technological and economic changes ...
  • Scarrott, G. G. (Computer Society of South Africa (on behalf of SAICSIT), 1980-03-01)
    The era of information engineering was initiated some thirty years ago by the demonstration of the first stored program electronic computer. At that time there was intense innovative excitement among the pioneers which, ...
  • Postma, S. W. (Computer Society of South Africa (on behalf of SAICSIT), 1980-03-01)
    The language LISP 1.5 is neither easy to write nor to read. In the McCarthy et al. definitive manual on LISP 1.5 a higher level language, MLISP, is used From the early 1960's various people have proposed higher level ...
  • Williams, M. H. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    BASIC and Pascal are two rather different programming languages, both of which have proved to be very popular. A new language BPL has been designed as an interactive programming language based on these two languages, ...
  • Turton, T. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    A new approach is proposed for the management of operating system state data. Relational database concepts are suggested for the analysis and organization of this data, and a common central service routine is described ...
  • Roets, P. P. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    An algorithm is presented for sorting a random access file in place. The algorithm is unique in the sense that no auxiliary storage, apart from a number of buffers in the machine's high-speed memory, is required. In ...
  • King, M. C. F.; Naude, G.; von Solms, S. H. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    Aspects are discussed of the practical application of recent relational theory. The relevant definitions, extracted from vari01-1s papers, have been restated using a common notation. An attempt is made to describe ...
  • Day, B. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    The Integrated Data Base Management System (IDMS) originally had only a CO~C?L d~ta manipulation language (DML). Recently a DML for FORTRAN on the 2900 series of ICL computers has been produced. This 1s a piece of software ...
  • Danhof, K. J.; Smith, C. L. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    This paper considers the emerging role of the microcomputer laboratory in a computer science department The components for a particular laboratory are suggested. These include the microcomputers themselves, supporting ...
  • Bishoo, J. M.; Currin, D. C.; Varol, Y. L. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    Emily is a general purpose computer aided instruction language with a novel implementation. At the user's level, Emily consists of two languages: an instruction language, which is used by authors to prepare lessons, and ...
  • Christensen, A. H. J. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    An algorithm is presented here that approximates a given surface A by a set of regular or semi-regular faces forming a polyhedron C. If the faces are all square, C assumes the aspect of a 'blocked' surface. It is also ...
  • Calingaert, P. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    To many persons, computer-assisted instruction (CAI) connotes automated programmed instruction (PI). This exemplifies the authorcontrolled mode of CAI, in which PI, suitably generalized, is mediated by the computer. This ...
  • Anderssen, E. C. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    Die probleme wat vandag gerekenariseer word is van so 'n ingewikkelde aard, datdie programmeringsproses self ook uitermate ingewikkeld geword het Ten einde die programrneerder in sy taak by te staan is heelwat "werktuie ...
  • Rodd, M. G. (Computer Society of South Africa (on behalf of SAICSIT), 1979-06-01)
    The efficient use of multiprogrammed industrial control computers is largely a function of the relationship between hardware and software. A shift in this relationship is desirable, since multi-programmed computers typically ...
  • Radue, J. E. (Computer Society of South Africa (on behalf of SAICSIT), 1979-06-01)
    The benefits associated with text compression include more efficient use of peripheral devices. faster information transfer rates and, in some cases, improved sorting speeds through the use of shorter sort keys. However. ...
  • Phillips, N.C.K. (Computer Society of South Africa (on behalf of SAICSIT), 1979-06-01)
    Despite intensive research the P = NP question is unresolved and the research suggests that it is hard to answer. The corresponding question for query machines with recursive oracles is undecidable in set theory. Simply ...
  • Peberdy, H. J. (Computer Society of South Africa (on behalf of SAICSIT), 1979-06-01)
    The past five years have seen a dramatic change about in traditional hardware/software relationships: hardware costs have plummeted, and the size, environmental requirements and reliability of computing elements have altered ...
  • Heher, A. D. (Computer Society of South Africa (on behalf of SAICSIT), 1979-06-01)
    This paper is concerned with the problems of interactive computing when multiple real-time tasks are involved. The interactive facilities which can be provided are described and some of the important software engineering ...
  • Penzhorn, A. (Computer Society of South Africa (on behalf of SAICSIT), 1979-09-01)
    Die keuse van 'n geskikte leerorganisasie vir 'n rekenaarstelsel is nie altyd eenvoudig en voor die hand liggend nie. In die geval onder bespreking moet 'n geskikte leerorganisasie gekies word vir 'n teksverwerkingstelsel ...
