Abstract

PURPOSE:To reduce the number of times of comparison operation for retrieval of a 16-bit character string to a half by automatically discriminating whether each of characters constituting the character string as the processing object conforms to the 8-bit code system or the 16-bit code system. CONSTITUTION:An operator selects the 8-bit code system or the 16-bit code system as the code system of each character as the processing object by a character string type defining part 1 and stores the selected code system in a character string type storage part 2 and temporarily stores a corresponding character string in a character string input part 3. The head address of character string data is calculated in a character string storage part 4, and simultaneously, the character string to be retrieved is inputted from a retrieval indicating part 5 to the storage part 4 and is compared, and a retrieval control part 8 refers to contents of the storage part 2 to start an 8-bit character string retrieving part 6 or a 16-bit character string retrieving part 7 according as said contents are '8' or '16'. Thus, the comparison processing of 8 bits and that of 16 bits are selected to reduce the number of times of operation to a half, and accidental coincidence error on the way of retrieval is eliminated.
