Hardly exciting, I know. Now, imagine that you need to insert an item
between ``call dentist'' and ``lunch with spouse''. Although it is as
easy as inserting one more writeln statement, you have to
renumber all the items after ``lunch with spouse''. It'd be nice if
somehow the program can automatically count the number of points.
With variables, the program can.
