Is it possible to put a class (not an instance) in a variable or array

I'm defining a hierarchy of classes and it would be convenient if it
were possible to register the fact that a class had a particular
subclass, such that the information was available before instantiation.
I'm assuming that the code that inspects the array has imported all
units so is aware of the relevant class declarations, but I am still
having problems with calling class methods and/or casting to a class
(as distinct from an instance).
Are you looking for something like this?:

No, I'm doing something simpler- setting up a sequence of classes to
mimic the definition of a node in an SNMP MIB file. I've got to the
point where I can query (the Pascal transcription of) a MIB file to find
out what nodes it implements and can work backwards and forwards to list
the OIDs associated with a node and its ancestors-descendants- all
without instantiating anything.
