-------------------
-- PARAMETER REFERENCE
-------------------

-- THIS TEST EVALUATES THE CODE EFFICIENCY OF REFERENCING A FORMAL
-- PARAMETER OF MODE IN OUT.

-- THE TEST VERSION INCLUDES THE DATA REFERENCE TO BE EVALUATED BY ASSIG
-- ING A FORMAL PARAMETER, PARAMETER, TO THE GLOBAL VARIABLE.  PRIOR TO
-- ASSIGNMENT, CAMOUFLAGED ASSIGNMENTS ARE MADE TO BOTH THE PARAMETER AN
-- TO THE GLOBAL VARIABLE.  THE GLOBAL VARIABLE IS USED IN A CONDITIONAL
-- MENT TO GUARD THE TEST ASSIGNMENT FROM OPTIMIZATIONS.  BECAUSE OF THI
-- GUARD, THE PARAMETER MUST BE UPDATED WITH ITS INITIAL VALUE SINCE
-- THE CONDITIONAL EXPRESSION MUST BE DYNAMICALLY EVALUATED.  ADDITIONAL
-- CAMOUFLAGED ASSIGNMENTS ARE MADE TO MAINTAIN THE VALIDITY OF THE
-- CONDITIONAL STATEMENT AND TO PREVENT ELIMINATION OF THE OTHERWISE
-- UNREFERENCED PARAMETER IN THE NOISE VERSION.

-- THE NOISE VERSION IS IDENTICAL TO THE TEST VERSION EXCEPT THAT THE TE
-- REFERENCE TO THE PARAMETER IS REMOVED SO THAT THE CODE EFFICIENCY
-- METRICS FOR THE PARAMETER REFERENCE CAN BE DERIVED AS A PART OF THE
-- ASSIGNMENT.
