Before you begin this lesson, you should read section 6.4 of the text.
In this lesson we will look at what happens when arrays are passed as arguments to functions and subroutines. It should not be surprising that it is possible to pass arrays as arguments. Arrays would be virtually useless otherwise, since all but the tiniest programs are composed of many functions and subroutines.
As usual, we need to copy some files before we begin.
