2. For an address in another data area, the number of addresses from the be-
ginning of the search is written to D+1. For example, if the address contain-
ing the minimum value is IR 114 and the first word in the search range is
IR 014, then #0100 is written in D+1.
If bit 14 of C is ON and more than one address contains the same minimum val-
ue, the position of the lowest of the addresses will be output to D+1. The position
will be output as the DM address for the DM area, but as an absolute position
relative to the first word in the range for all other areas.
The number of words within the range (N) is contained in the 3 rightmost digits of
C, which must be BCD between 001 and 999.
When bit 15 of C is OFF, data within the range is treated as unsigned binary and
when it is ON the data is treated as signed binary.

Caution
If bit 14 of C is ON, values above #8000 are treated as negative numbers, so the
results will differ depending on the specified data type. Be sure that the correct
data type is specified.

When IR 00000 is ON, the control data in DM 0300 (4010) will cause a search for
the maximum value in the 10 words starting at DM 0000. The smallest unsigned
