Index modification when using extended data register in LCPU

When I use internal user device (D) and extended data register (D) in LCPU, and specify an extended data register (D) area using index modification, an error with an error code 4101 occurs. What is the remedy?

Example)
- Internal user device: D0-8191
- Extended data register: D8192-315391

If Z0=10000 is specified when "D100Z0" is written, an error occurs.

Answer

It is not possible to specify index modification to cross over the boundary between the internal user device (D) and the extended data register (D).
Change the internal user device (D) to 0 point and set all to the extended data register (D) allows index modification.
