A user-oriented Computer Graphics System (CGS) is described, which primarily has been designed to aid the application programmer, and not just the sophisticated computer graphics user. The system has been designed to provide a very simple interaction capability, where the interaction is based on a variety of input devices and a simple input/output graphics command language. The result of this system has been an increase in programming efficiency, reduction in span time from creations of design to actual implementation. Typical application developments have included such system as flowcharting systems, Computer Aided Architectural Space Planning, Animation, Vehicle-Pedestrian Interactions, Computer-aided designs, and the simulation of the NASA Space Shuttle.
This paper presents a methodology for the design and verification of a class of real-time systems frequently encountered in applications of digital control. These methodologies are described in the form of a design an...

An important aspect of the original implementation of APL\360 was the treatment of arithmetic functions as abstract functions defined on the continuous set of real numbers [1,2]. This had various consequences, including automatic conversion between different machine representations of numbers so that storage and other aspects of System/360 architecture could be used efficiently while suppressing its details. [2]“Fuzzy” comparisons were introduced so that the actual discrete, fixed-precision, hexadecimal representation could be partly disguisedThe technique used in the original implementation was to regard numbers whose difference was zero in the first twelve (of fourteen) hexadecimal digits to be equal. The definitions in [3] were developed by M. A. Jenkins and R. H. Lathwell in 1968 when it was found that, for some values, implications of relational functions such as B> A←→~ B≤ A were violated. It was later discovered that these definitions did not completely correct the difficulty, and when APL system variables were introduced [4], the tolerant functions were rederived, resulting in the definitions given here.
The software design process is discussed from an engineering point of view. Initially, a distinction is made between software design and program design. Software design is then described in terms of evolving a system ...
