====Instance Environment (first character = &)====

Instance variables are preceded by the ampersand character <code>&</code>.

No special variables are defined for the instance environment. A programmer should take care about variables used in base classes and about the fact that instance variables can also be accessed and changed from outside the class/instance e.g. by using <code>instancename.variablename</code> in a <code>READ</code> command or an assignment statement.
