(S1) as a keyword. Then, the number of matches with the keyword is stored at the device designated by (D)+1, and the first
matched device number (in the relative number from (S2)) is stored at the device designated by (D).
• No processing is conducted if n is 0 or a negative value.
• If no matches are found in the search, the devices designated at (D) and (D)+1 become "0".
(S1): Search data or head number of the devices where the search data is stored (BIN 16/32 bits)
