Region Recognition Using Area Method

Visual aids in the form of graphs and charts are often used in analysis and design procedures. Commonly, a graph is divided into regions of common characteristics, such as in a soil classification scheme in which a set of properties are located on a chart and the soil classification is given. Although these aids are useful in hand calculations, it is often difficult to implement these charts into a computer code. A general technique is described in this paper which can simplify both implementation and the regional coordinate analysis by the use of an area coordinate method. An example and a short Fortran code are also included to show how this technique can be used.     

An Interactive Shell for Batch Programs

Many programs have been and are currently being developed in which the input files or associated data bases must be produced independently of the main program. This article describes two programs which are used to develop an interactive, menu-driven system of input prompts which is then used to create and maintain information files for other programs. The two program system provides an easy method to develop well-structured, interactive input programs without the high development costs required to write original code. Graphics can be developed for any input screen and a command language can be specified for data output. Two examples are provided to present an overview of the system.
