Abstract
Formex algebra is a powerful tool for the generation of data used in the design and analysis of space structures. However, for the algebra to be of practical use, it is necessary to have a means of employing the concepts on a computer. This is the particular problem which this thesis addresses. The solution proposed here is Formian, an interactive programming language, which being modelled on formex algebra allows complex configurations to be generated from a few concise and yet readily understood statements. Formian is designed to allow problems of data generation to be tackled in a single programming environment. The thesis describes the raison d'etre for the Formian programming language and the steps taken to create the language and to provide a practical and reliable implementation in the form of a computer program. A complete description of the language structure is given. This includes an overview of formex algebra. The use of Formian from a designer's viewpoint is provided by interspersing the description with practical examples.
