6. Define the term stack frame and list the things it contains.

7. Describe the difference between passing arguments by value and passing them by reference and give an example of each.

8. List the steps required to use procedures that utilize parameters passed on the stack and local variables.

9. Write a procedure called CalcAv that accepts three DWORD values and returns the value of (three + the first number) minus (six + the second number) + (two times the sum of the three numbers) where three, six and two are local variables in the procedure.
