Abstract

PURPOSE:To realize a suitable string operation to finish a string operating instruction by detecting the value '0' of the string component element in addition to the element number. CONSTITUTION:A main memory 310 includes a machine word program 311 and a data area 312. A CPU 320 gives an access to the memory 310 and at the same time refers to and replaces the value of the area 312 based on an instruction of the program 111 to carry out the data processing. In this case, the processing of a string operating instruction is finished by the state of the value of the string component element in addition to the number of string elements. In other words, the specific value like '0', etc., is added to the end of the string to show the end of the string. Thus it is possible to finish the string operating instruction even with such a string that designates indirectly the number of string elements. As a result, a string operation is suitably carried out with an information processor.
