	To my fellow C nerds,

	It's been a  great manny years since I wrote this appended
	snippet.  Now I can't remember why (of if ) I need all the
	strcpy() calls.   Is there a simpler, more logical way of 
	printing a bunch of string by snipping off the left-most?

	In short,, can anyone 'splain why strtok needs all this?

	tia,

	gary
