+-- Description :
+-----------------------------------------------------------------------
+-- this test checks the correctness of the record declaration as a type
+-- it also checks for the usage of the record element declarations.
+-- the assert statement is also checked.
+-- the record is declared within a package
+-- the test also checks the correctness of the function impelmentation.
+-- the function accepts the record parameters and returns the result of 
+-- type real.
