ENUM             Define enumerated type                             Directive

  ENUM name [enum_var [,enum_var...]]   ; Ideal mode
  name ENUM [enum_var [,enum_var...]]   ; MASM mode

    Declares an enumerated data type. The syntax of each enum_var is:

       var_name [=value]

    An enumerated data type represents a collection of values that can be
    stored in a certain number of bits. The maximum value stored
    determines the actual number of bits required.

    Turbo Assembler will assign a value equal to that of the last variable
    in the list plus one if =value isn't present when you assign the
    specified value to the variable var_name. Values can't be relative or
    forward-referenced.

    Enumerated data types are redefinable. Variables created with ENUM are
    redefinable numeric variables of global scope.

    Example:    ENUM corners    north, east, south, west
                ENUM fkeys      f1 = 3bh, f2, {
                                f3, f4
                                f8 = 42h, f9
                                f10, f11, f12 }

    Turbo Assembler provides special support for record fields that
    represent flags and enumerated data types (see GETFIELD, SETFIELD,
    MASKFLAG, SETFLAG, TESTFLAG, FLIPFLAG).


    Creating an instance of an enum

    You can create an instance of an enumerated data type by using the
    name of the enumerated data type as a data allocation directive.

    Enumerated data type instances are always either a byte, a word, or a
    doubleword, depending on the maximum value present in the definition.

    Examples:   direcs corners  south           ; Initialized to south
                direc2 corners  315             ; Value outside fits OK
                direc3 corners  ?               ; Uninitialized
