Index and data registers

Can you help me how this data register and index registers works together. Storing CIO/DM to IR then using DR for IR pointer. 

then how this mov digit instruction works to index registers and data register.

Ex: movd Dr0,IR0 #210 DR1,IR1

upon checking of the values in dr1 and ir1, seems nothing happen.

Dr0,Ir0 didnt move to Dr1,Ir1

Thanks in advance.
