Class Pointer

[David A. Osborn]

I have a set of classes that each have an enumeration in them, and based on
dynamic input I need to access a different enumeration. For example

Three classes Class_A, Class_B, and Class_C that all have a different
enumeration in them called Properties. I want to basically have a variable
The_Class that I can dynamically point to either Class_A, Class_B, or
Class_C and then do The_Class.prope rties to get the correct enumeration.
How would I define the Class point variable and load it to the correct
class?
