-- This package provides output routines for integer dimensioned types. All
-- Put routines are modelled after those in package Ada.Text_IO.Integer_IO
-- with the addition of an extra default parameter. All Put_Dim_Of routines
-- output the dimension of Item in a symbolic manner.
-- Parameter Symbol may be used in the following manner (all the examples are
-- based on the MKS system of units as defined in package System.Dim.Mks):
-- type Mks_Type is new Integer
-- with
-- Dimension_System => (
-- (Unit_Name => Meter, Unit_Symbol => 'm', Dim_Symbol => 'L'),
-- (Unit_Name => Kilogram, Unit_Symbol => "kg", Dim_Symbol => 'M'),
-- (Unit_Name => Second, Unit_Symbol => 's', Dim_Symbol => 'T'),
-- (Unit_Name => Ampere, Unit_Symbol => 'A', Dim_Symbol => 'I'),
-- (Unit_Name => Kelvin, Unit_Symbol => 'K', Dim_Symbol => "Θ"),
-- (Unit_Name => Mole, Unit_Symbol => "mol", Dim_Symbol => 'N'),
-- (Unit_Name => Candela, Unit_Symbol => "cd", Dim_Symbol => 'J'));
-- Case 1. A value is supplied for Symbol
-- * Put : The string appears as a suffix of Item
-- * Put_Dim_Of : The string appears alone
-- Obj : Mks_Type := 2;
-- Put (Obj, Symbols => "dimensionless");
-- Put_Dim_Of (Obj, Symbols => "dimensionless");
-- The corresponding outputs are:
-- $2 dimensionless
-- $dimensionless
-- Case 2. No value is supplied for Symbol and Item is dimensionless
-- * Put : Item appears without a suffix
-- * Put_Dim_Of : the output is []
-- Obj : Mks_Type := 2;
-- Put (Obj);
-- Put_Dim_Of (Obj);
-- The corresponding outputs are:
-- $2
-- $[]
-- Case 3. No value is supplied for Symbol and Item has a dimension
-- * Put : If the type of Item is a dimensioned subtype whose
-- symbol is not empty, then the symbol appears as a suffix.
-- Otherwise, a new string is created and appears as a
-- suffix of Item. This string results in the successive
-- concatenations between each unit symbol raised by its
-- corresponding dimension power from the dimensions of Item.
-- * Put_Dim_Of : The output is a new string resulting in the successive
-- concatenations between each dimension symbol raised by its
-- corresponding dimension power from the dimensions of Item.
-- subtype Length is Mks_Type
-- with
-- Dimension => ('m',
-- Meter => 1,
-- others => 0);
-- Obj : Length := 2;
-- Put (Obj);
-- Put_Dim_Of (Obj);
-- The corresponding outputs are:
-- $2 m
-- $[L]
-- subtype Random is Mks_Type
-- with
-- Dimension => ("",
-- Meter => 3,
-- Candela => 2,
-- others => 0);
-- Obj : Random := 5;
-- Put (Obj);
-- Put_Dim_Of (Obj);
-- The corresponding outputs are:
-- $5 m**3.cd**2
-- $[L**3.J**2]
