Example
If bit 14 of C is ON and more than one address contains the same maximum 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.

C:
Not used – set to zero.
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.
Indirectly addressed DM word is non-existent. (Content of *DM word is
ER:
not BCD, or the DM area boundary has been exceeded.)
R and R +N–1 are not in the same data area.

EQ: ON when the maximum value is #0000.
When IR 00000 is ON, the control data in DM 0000 (4010) will cause a search for
the maximum value in the 10 words starting at IR 200. The largest unsigned val-
