B,D Correct answer
Explanation

In JCL procedure parameter override, PGM parameters CANNOT be overridden on EXEC statements. New parameters that don't exist in the procedure can be added dynamically. All parameters for each step must be coded in the correct order as they appear in the procedure, though this is a common source of confusion.
