Enumerations

Enumerations are types that inherit from System.Enum. The elements of an enumeration
are expressed in words rather than numbers, which makes it convenient for understanding
the meaning of the value being used. Enumerations symbolically represent a set of values
of one of the primitive integral types.
The type of the elements of an enumeration can be Byte, Short, Integer or Long. If no
type is specified explicitly, the default type is Integer.

Example:
Enum month As Byte
Jan = 2
Feb = 5
Mar = 10
End Enum


Explanation:
In the above code segment, an enumeration type month is declared. The underlying type
of the elements has been specified as Byte. It has three elements viz: Jan, Feb and Mar.
These three elements have been assigned specific values. In case of an enumeration, if no
values are specified, the value of the first element corresponds to 0 and so on.
