When the history stack has reached its maximum size, the top command on
the list is deleted as each new command entered is added to the bottom of
the list.  Consecutive numbering of the commands continues until the
session ends.

Exercises

     history stack.  Try entering a misspelled command.  How is it
     recorded in the history stack?

7.   Given a maximum history stack size of 20, what range of numbers will
