	1. This program shows you a typical way of handling
	   command-line arguments.  Run this program with various
	   combinations of command-line arguments--none, one, two,
	   etc.  Try it with one argument using the name of an
	   existing text file, and then try it with one argument
	   using a non-existent file name.
	 
	2. What happens if you remove the "if( argc != 2 )" test
	   and you run the program with no arguments?  Is it the
	   same on the white and black NeXTs?
