------------------------
-- Parameter Association 02
------------------------

-- This test evaluates the code efficiency of a call to a procedure that
-- has two formal in out parameters of the same generic formal type.

-- The procedure Param_Assoc is called in the test version using local
-- variables, Outer_1 .. Outer_2 as the actual parameters.  These
-- variables are referenced inside the procedure through the formal
-- parameters to ensure that the required parameter passing is
-- performed.

-- In the noise version, the procedure Param_Assoc is parameterless
-- and references only the local variables, Local_1 .. Local_2, so that
-- there is no parameter passing overhead incurred.  Both the test and
-- noise versions perform the same camouflaged assignments to outer and
-- local variables, respectively.

-- The purpose of using local variables in the noise version is to
-- avoid uplevel referencing of the outer variables.  To prevent the
-- elimination of the local variables in the test version, the values
-- of the locals are used in the assignments just as they are in the
-- noise version.  The same number of assignments are performed in both
-- versions.
