Nice example.

Mr.Michael Karas why the following is used and cannot understand the explaination as you have given in your answer at that link;


CALL_TABLE:
CLR C ;
RLC A ; multiply * 2 for word access
MOV R0, A ; save a copy of index
INC A ; increment index to the hig byte
MOVC A, @A+DPTR ; low byte
PUSH ACC ; onto stack
MOV A, R0
MOVC A, @A+DPTR ; high byte
PUSH ACC ; onto stack
RET ; direct branch to the subroutine

END
