[Original article not included for brevity--type `p' if you want to see it]

There have been several people who suggested that it would be nice if C had
non-zero origined arrays.  How about the following (albeit kludgy)
solution:

	int a[21];	/* really meant to be a[ -10 .. 10 ] */
	int *na;	/* na stands for new-a, good software engineering
			   type descriptive variable name :-) */

	na = &a[10];	/* na[-10] is now a[0], na[0] is a[10], etc. */
