This tutorial introduces and explains the features of the Vispatch
visual programming language. The tutorial makes use of a Java applet
that allows readers to interactively experiment with actual
Vispatch programs. Readers can also use the Java applet to experiment with the
various aspects of the Vispatch language as they are introduced
throughout the tutorial. The tutorial first introduces Vispatch using three example programs, with which readers may experiment using the Java applet. These programs quickly illustrate some of Vispatch's interesting properties as a visual language. The next part of the tutorial explains the applet's editing features. These features will be useful for experimenting with Vispatch programs. The complete Vispatch visual language is then explained in detail. After each component is introduced, a simple Vispatch program is presented that demonstrates the component. The final part of the tutorial shows other uses of Vispatch that illustrate interesting programming language properties and research directions. |
