An enumeration represents a list of constant values, such as values for the days of the week. You can declare an enum type that defines the values and symbolic names for them. You can then refer to the values by name.

enum-id Action.
   78 #Start.   *> Start is a reserved word so use '#' symbol
   78 #Stop.
   78 #Rewind.
   78 #Forward.
end enum.

enum-id Status.
   78 Flunk value 50.
   78 Pass  value 70.
   78 Excel value 90.
end enum.

class-id MainClass.
method-id main static.
   declare a = type Action::Stop
   if a not = type Action::Start
       display a & " is " & a as binary-long   *> Prints "Stop is 1"
   display type Status::Pass as binary-long    *> prints 70
   display type Status::Pass *> prints 
end method.
end class.

Further Information

The Compiler adds a static method called 'values' that returns an array containing the values of the enum. You can use this method together with the PERFORM THROUGH construct to iterate over the values of an enum type.

The enum-header is followed by a working-storage section consisting of:

  • A single numeric field of one of the predefined types. By default, this is binary-long.
  • Any number of level 78 items defining the values for the enum. The default value of the first item is 0 and the values of subsequent items are incremented by default.
Note: In COBOL for .NET, you can set the attribute System.FlagsAttribute. This attribute applied to an enum means that the distinct values are to be regarded as bit settings, and can therefore be combined. For example:
enum-id MyFlags attribute System.FlagsAttribute.
