PURPOSE:To attain the write of a designated padding character in a designated storage area, by providing newly a clear exclusive instruction and executing this instruction. CONSTITUTION:Whether or not a remaining byte number is <8 is checked in case of the clear exclusive instruction, and when Yes, the processing of (7) is executed, and if No, the processing of (5) is executed. Further, the padding character is transferred in the unit of 8-byte. Then, ''8'' is subtracted from the remaining byte number and the processing is restored to the (4). Further, whether or not the remaining byte number is 0 is checked as shown by the step (7). When Yes, the processing is finished and if No, the processing of (8) is executed. Then, the character is transferred in the unit of 1-byte. Then, ''1'' is subtracted from the remaining byte number as shown by the step (9). Moreover, the 1st 1-byte (head type) designates the padding character, the 2nd byte desginates a space, and the 3rd and the 4th bytes designate the length of byte to be cleared. |
