minimum value are searched
(s2) Data to be searched for or device number storing data
(d) Head device number storing number of same data, maximum
value and minimum value detected by search
(n) Number of data in which same data, maximum value and
minimum value are searched

Processing details
• These instructions search the same data as the 32-bit binary data of (s2)+1 and (s2) in (n) data starting from (s1)+1 and
(s1), and store the search result in (d)+1, (d) to (d)+9, and (d)+8.
• When the same data exists, five 32-bit binary data devices starting from (d)+1 and (d) store the number of same data, first
position, last position, maximum value position and minimum value position.
• When the same data does not exist, five 32-bit binary data devices starting from (d)+1 and (d) store the number of same
data, first position, last position, maximum value position and minimum value position. In this case, however, 0 is stored in
three 32-bit devices starting from (d)+1 and (d) (which store the number of same data, first position and last position).
