Operating as a practical guide for learning functional programming directly through the diagrams used to define functions, this book describes, and provides access to, a system that gives a level of support akin to that provided in word processing.

Schematic functional programming uses diagrams, this book is the first to demonstrate a professional programming language based on a combination of both schema and functions

Drawing Programs: The Theory and Practice of Schematic Functional Programming describes a diagrammatic (schematic) approach to programming. It introduces a sophisticated tool for programmers who would rather work with diagrams than with text. The language is a complete functional language that has evolved into a representation scheme that is unique. The result is a simple coherent description of the process of modelling with the computer. The experience of using this tool is introduced gradually with examples, small projects and exercises. The new computational theory behind the tool is interspersed between these practical descriptions so that the reasons for the activity can be understood and the activity, in turn, illustrates some elements of the theoryAccess to the tool, its source code and a set of examples that range from the simple to the complex is free (see springer.com/978-1-84882-617-5). A description of the tool's construction and how it may be extended is also given.The authors' experience with undergraduates and graduates who have the understanding and skill of a functional language learnt through using schema have also shown an enhanced ability to program in other computer languages. Readers are provided with a set of concepts that will ensure a good robust program design and, what is more important, a path to error free programming.
