Processing details
■MAX
• Searches in the n points of 16-bit BIN data, from the device designated by (S), for the maximum value and stores the
searched maximum value at the device designated by (D).
• Starts the search from the device designated by (S) and stores the location, specified in the number of points counted from
(S), of the device where the maximum value is found first at (D)+1 and stores the number of the found minimum values at
(D)+2.

■DMAX
• Searches in the n points of 32-bit BIN data, from the device designated by (S), for the maximum value and stores the
searched maximum value at the device designated by (D) and (D)+1.
• Starts the search from the device designated by (S) and stores the location, specified in the number of points counted from
(S), of the device where the maximum value is found first at (D)+2 and stores the number of the found minimum values at
(D)+3.
