Interactive Teaching Materials in PDF using JavaScript

The use of JavaScript scripting language for adding interactivity to portable teaching materials of a high typographical quality in PDF file format is described. An extended version of the program TEX called pdfTEX is extremely useful for such purposes. It is shown that applications similar to those done by a CGI scripting on the web can be done in PDF, exploiting Acrobat forms and the embedded JavaScript engine implementation in Acrobat Reader or other PDF viewers.
