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 {
    Zero
    One
}

If a value is assigned to a name, the sequence will continue from that point. The following example starts with the value 5; Six will automatically be given the value 6:

enum MyEnum {
    Five = 5
    Six
}

Automatic value assignment supports non-contiguous sets. The sequence may be restarted at any point, or values may be skipped. The following example demonstrates both restarting a sequence and skipping values in a sequence:

enum MyEnum {
    One   = 1
    Two
    Five  = 5
    Six
    First = 1
    Second
}

This example mixes two potentially different name sets in a single enumeration to demonstrate restarting the numeric sequence. This should be avoided outside of demonstrations as it makes the use of the enumeration ambiguous.
