8051 have the instruction
movc a, @a+dptr
movc a, @a+pc

to make the job in accessing code array easy.

However, it doesn't provide the instruction for accessing data array (in chip).

What I do is pass array index into r0 and the base data address into r1. The call a routine and give me
r0 = address of code[index]

I can access the data array by
mov ANYWAY, @r0

Is there any better technique that you can share with me.

thanks.
