As you work with Vensim, you have several valuable resources at your fingertips. The Pullout Reference card shows the names and operations of buttons found in the main Vensim window. This User's Guide is complemented by the Modeling Guide and the Reference Manual. The Modeling Guide describes the development of a number of different dynamics models and goes into some more advanced modeling techniques. The Reference Manual provides in-depth coverage of all the features and operation of Vensim. There is a Vensim DSS Reference Supplement that documents capabilities unique to Vensim DSS. All of these manuals are available as on-line help, which facilitates searches on particular topics.
