-2- THE DIFFERENT TYPES.

   Declaring a variable is to attribute a symbolic name to a memory place.
   We also have to indicate its TYPE. The type of a variable determines
   the values it can have, the operations which can be performed upon it
   and its memory restrictions. The TYPE DECLARATION specifies the
   identifier of the chosen type.

   DECLARATION OF A TYPE ---> identifier = TYPE ;

   THE SIMPLE TYPES:

        The simple types define groups of ordinal values.

        simple type -> scalar type
                    -> real type

        An identifier of the REAL type is one of the following standard
        identifiers:
                - REAL
                - SINGLE  (simple)
                - DOUBLE
                - EXTENDED
                - COMP    (composite).

   THE SCALAR TYPES:

        These types are sub-sets of the simple types class.
        All simple types other than reals are scalar types.
        The possible values of a scalar type form an ordinal row.
        Except the integer type, the first value always is of zero range.
        Turbo Pascal handles 7 predefined scalar types:
           - INTEGER
           - SHORTINT    (short integer)
           - LONGINT     (long integer)
           - BYTE
           - WORD
           - BOOLEAN
        The user can also define two other types:
           - ENUMERATED
           - SUBRANGE    (interval-type)
