Typical of the preferred embodiment, a four digital word group comprising W.sub.a, W.sub.b, W.sub.c, and W.sub.d, and representing four mutually contiguous searched space segments is used to produce the average of W.sub.a and W.sub.b, the average of W.sub.a and W.sub.c, and the average of all four in the group. The averages and the memory words are painted on a display in their appropriate locations.
