Which manual are you getting that from? I have the PDF documentation for FPC, but I can't seem to find the section you're referencing.

It seems that is referencing procedural variables, but I'm talking more about a "objective" variables. AKA, a pointer to a type. For instance all types descend from the base type, and the standard base constructor is called by a lookup table. That's pretty much what I'm after.

But I guess I could achieve something similar through a case statement and a class-type integer. :?
