The use of SYMMETRICA 
The aim of this chapter is a rough description how you can write your
own program using SYMMETRICA . 
We therefore provide a brief description of
a few very easy  and basic examples before going deeper into details 
in the following
chapters.
We should like to introduce the reader in particular to object oriented programming. The
aim is to put her or him in a position to write more sophisticated programs on her or his own.
