摘要:

AbstractThis paper proposes graphics primitives for constructing programs for algorithm animation. Our experiments show that these primitives can reduce program development time. Future directions of the current research is also discussed.

摘要:

AbstractThis paper describes a visual command language for a workstation with a bit‐mapped display and a mouse that can be used to create different user interfaces. Primitive interface components can be combined into more complex user interfaces. The user specifies interconnections between these components over which data and commands can be sent by pointing with a mouse.Primitive interface components are described for creating several different database user interfaces. The design and implementation of the software architecture is described, including the primitives for database interfaces and the communication protocols used by the syste

摘要:

AbstractThe next revision of the standard Fortran language, commonly referred to as Fortran 8x, has now been published, at least in draft form. It is therefore possible for some of its new features to be investigated and the type of programming that can be expected when implementations appear to be explored. This paper looks at the scope provided by the proposed new features for 'semantic extension' of the language. The capability is illustrated by way of example code which could provide an extended‐precision numeric facility if implemented. The new linguistic constructs that permit this type of approach to software provision are described as they are use

摘要:

AbstractThis paper defines a programming language for distributed processing called Joyce. Joyce is based on CSP and Pascal. A Joyce program defines concurrent agents which communicate through synchronous channels. The agents may be recursive.

摘要:

AbstractJoyce is a programming language for parallel computers based on CSP and Pascal. A Joyce program defines concurrent agents which communicate through unbuffered channels. This paper describes a multiprocessor implementation of Joyce.

摘要:

AbstractTo allow tools in a computer‐based working environment to share data, it is sometimes necessary to transform the data from the form used by one tool to the form expected by another. An application generator has been developed that generates data transformation programs from high‐level descriptions of the required transformations. The transformation specifications are expressed in traditional set notation, which combines features of functional and logic programming. The system thus offers a powerful declarative language for expressing data transformati
