PURPOSE:To obtain a decimal access code by forming 4<n> square mesh divided areas in accordance with mesh dividing levels based upon hexadecimal numbers, reading out the access code of a required specific area as a hexadecimal number and converting the hexadecimal number into a decimal number. CONSTITUTION:A specific area is equally divided into four parts respectively in vertical and horizontal directions to form sixteen large-scale divided areas and a hexadecimal number consisting of divided area specifying codes ''0''-''F'' is assigned to respective areas. Each large-scale divided area is equally divided into four parts respectively in the vertical and horizontal directions to form sixteen medium-scale divided areas and hexadecimal numbers consisting of the divided area specifying codes ''0''-''F'' are assigned to respective areas. Then, each medium-scale divided area is equally divided into four parts respectively in the vertical and horizontal directions to form sixteen small- scale divided areas and hexadecimal numbers consisting of the divided area specifying codes ''0''-''F'' are assigned to respective divided areas. Thus, a decimal access code corresponding to the required specific divided area can be found out by reading out the access code of the required specific divided area out of many square mesh divided areas as hexadecimal number corresponding to the mesh dividing level and converting the hexadecimal number into a decimal number. |
