Automatic value assignment

An enumeration may be created without defining a value for a name. PowerShell will automatically allocate a sequence of values starting from 0. In the following example, the names Zero and One are automatically created with the values 0 and 1, respectively:

enum MyEnum {    Five = 5    Six}
