Scripts can use extern variables to store status values and for interaction between
scripts. The extern variables can be declared in a script triggered by the Open event,
and deleted in a script triggered by the Close event.

Extern variables can also be used in object graphs, where several object graphs can be
opened concurrently. Mix-up of the variables is avoided by setting the namespace for
extern variables to the instance object name. Supply the instance object as argument and
set the namespace with set_namespace(p1).
