2) Index settings that cross file registers (ZR), extended data registers (D), and
extended link registers (W)
Even when an index setting that crosses file registers (ZR), extended data
registers (D), and extended link registers (W) is applied, an error does not
occur.
However, if the result of the index setting applied to file registers (ZR),
extended data registers (D) or extended link registers (W) exceeds the range
of the file register files, an error occurs. (Error code: 4101)
Even when the index setting
that crosses file register and
extended data registers (D) is
applied, an error does not occur.
