Summarize the distinction between a machine language and an assembly language.

2.
Design an assembly language for the machine described in Appendix C.

John Programmer argues that the ability to declare constants within a program is not necessary because variables can be used instead. For example, our example of AirportAlt in Section 6.2 could be handled by declaring AirportAlt to be a variable and then assigning

it the required value at the beginning of the program. Why is this not as good as using a constant?
