	It has been my understanding, that in USE "*ptr[]" and "**ptr" are
	essentially the same and can be used interchangably.
	However, at initialization you have to declare the size of the array
	as David says above.	The reason that you can get away with
	"char *argv[]", is because the number of arguments that is passed
	to the program environment is know.(in argc)	Am I wrong?
