				register before running the
				program.
x	003-	43	11	Squares the contents of the X-
				register (which will be r).
$	004-	43	26

				r , the BASE AREA of a can.
O4	006-	44	4	Stores the BASE AREA in R4.
O+1	007-44,40, 1			Keeps a sum of all BASE
				AREAS in R1.
¦	008-		31	Stops to display BASE AREA
				and allow entry of the h value.
*	009-		20	Multiplies h by the BASE
				AREA, giving VOLUME.
´©	010-	42	31	Pauses briefly to display
				VOLUME.
O+2	011-44,40,		2	Keeps a sum of all can
				VOLUMES in R2.
l0	012-	45	0	Recalls r.
÷	013-		10	Divides VOLUME by r.
2	014-		2
*	015-		20	π
				2 rh, the SIDE AREA of a can.
l4	016-	45	4	Recalls the BASE AREA of the
				can.
2	017-		2	Multiplies base area by two (for
*	018-		20	top and bottom).
