The following comparison shows the relationship between input and output instances: Input
instance = output in 50d.

instance 162. Refer to appendix B for a more detailed view of the object model.

Access administration
The assembly object is a collection of attributes from classes 64h and 65h (input and output).
Both implicit and explicit access to these objects is possible (via the assembly object).
Simultaneous access is regulated as follows to prevent the attributes from overwriting one
another.
