The Enum-ID paragraph indicates that this Identification Division introduces
a enumeration definition and specifies the name that identifies the enumeration.
General Format

Syntax Rules
- Within an enumeration definition, the data division must consist of only
a Working-Storage section that defines exactly one data item that is an integer
.NET native type. The definition of this data item must be followed by level
78 entries defining constant-names, which may or may not include the VALUE
clause. If the VALUE clause is omitted, the constant has the value 1 if it
is the first constant, and otherwise the value of the previous constant +
1.
- A custom-attribute that equates to "System.FlagsAttribute" indicates that
the values specified are to be treated as bit settings, and can be combined
using logical AND and OR.
- Source units that wish to reference an enumeration definition must include
the enumeration defintion in a class-specifier in their REPOSITORY paragraph.
