Abstract
An (M plus K)-digit accessed address is checked to see if it may fall within a range of addresses g defined by the address at one end of the range plus a variable range of addresses (g). The checking is done in a single step in a comparison of the K lowest order address digits for both addresses. The K digits of the two addresses are checked against one another in two separate segments, a pointer segment and a range segment. The pointer segments of the two addresses are examined to see if any one of three relationships which would possibly place the accessed address within the range exists. The range segments of the two addresses are examined at the same time for an additional requirement to place the accessed address in the range.
