When certain bits are specified in a word device, bits other than the certain bits
that store the operation result do not change.
(3) The following program compares the value data stored at D0 to D5 with the value data
stored at D10 to D15, and then stores the operation result into M20 to M22, when M0 is
turned on. Also, the program transfers the character string "ALL ON" to D100 and up when
all devices from M20 to M22 have reached the on status.
