An error is returned in the following conditions. The error ag M8067 is set to ON to identify this error and
the error code is stored in D8067.
1. Error 6705 is returned when the number of stored data entries is out of range.
2. Error 6706 is returned when n > [D].
3. Error 6706 is returned when n ≤ 0.
4. Error 6706 is returned when [D] ≤ 0.
