 		 #126987 - SFRs rule!
Responding to: ???'s previous message
Jan,

Excellent solution. I'm waiting for the silicon vendors to implement this OFFSET_SFR.

And how could I have missed jmp @a+dptr. Somehow the instruction put a jumptable in my mind using an extra indirection. I expected it to read 2 bytes at a+dptr in code memory and jump to the address represented by those 2 bytes. Instead it jumps to the address a+dptr.

One learns something everyday.
