A processing system consisting of 11 programs, designed for management and analysis of vegetation data is presented. The concept of the system and the operational logic are discussed. Some of the main features are detailed. These include: (1.) availability of many methods, (2.) the possibility for the user to interact with the processing system by altering the analysis through options, and (3.) the computer supported handling of data, such as storing and retrieving data, subdividing or combining data sets, reducing the number of species or relevés, and printing tables and graphs. Differences between this and other program packages are discussed. It is shown that the data, not only the programs, can be made a part of the processing system.
