--- OBJECTIVE:
--- Check that, for both Float_Random and Discrete_Random packages,
--- the following are true:
--- 1) the procedures Save and Reset can be used to save the
--- specific state of a random number generator, and then restore
--- the specific state to the generator following some intermediate
--- generator activity.
--- 2) the Function Image can be used to obtain a string
--- representation of the state of a generator; and that the
--- Function Value will transform a string representation of the
--- state of a random number generator into the actual state object.
--- 3) a call to Function Value, with a string value that is
--- not the image of any generator state, is a bounded error. This
--- error either raises Constraint_Error or Program_Error, or is
--- accepted. (See Technical Corrigendum 1).
---
--- TEST DESCRIPTION:
--- This test evaluates components of the Ada.Numerics.Float_Random and
--- Ada.Numerics.Discrete_Random packages.
--- The first objective block of this test uses Procedure Save to
--- save the particular state of a random number generator. The random
--- number generator then generates a series of random numbers. The
--- saved state variable is then used to reset (using Procedure Reset)
--- the generator back to the state it was in at the point of the call
--- to Save. Random values are then generated from this restored
--- generator, and compared with expected values.
--- The second objective block of this test uses Function Image to
--- provide a string representation of a state code. This string is
--- then transformed back to a state code value, and used to reset a
--- random number generator to the saved state. Random values are
--- likewise generated from this restored generator, and compared with
--- expected values.
