| ObjectNumber[object] returns the value of $ObjectNumber during the definition of object. Every new object gets a new value for ObjectNumber[object]. Use New to create an object from a class template. |
This loads the package.
We first define some classes and objects.
Each object has a unique number.
If an object is removed, there is a hole in the numbering. Any unknown object gets the number zero.
Here is the list of all currently active objects.
