This instruction is available in the CPM2A/CPM2C only.
N must be BCD between 0001 to 9999.
R and R +N–1 must be in the same data area.

DM 6144 to DM 6655 cannot be used for D.
When the execution condition is OFF, MIN(––) is not executed. When the execu-
tion condition is ON, MIN(––) searches the range of memory from R
for the address that contains the minimum value and outputs the minimum value
to the destination word (D).
The address is identified differently for the DM area:
1. For an address in the DM area, the word address is written to C+1. For ex-
ample, if the address containing the minimum value is DM 0114, then #0114
is written in D+1.
