2.222. Object Data Type

Object variables are stored as 32-bit (4-byte) addresses that refer to objects. You can assign any reference type (string, array, class, or interface) to a variable declared as an Object.

An Object variable can also refer to data of any value type (numeric, Boolean, Char, Date, structure, or enumeration).
