Question

Develop a short sequence of instructions that adds AL, BL, CL, DL, and AH. Save the sum in the DH register

Answer 1

A short sequence of instructions that adds AL, BL, CL, DL, and AH and save the sum in the DH register is given below :

MOV AL , 10H    ; AL = 10H

MOV BL , 20H   ; BL = 20H

MOV CL , 30H   ; CL = 30H

MOV DL , 40H   ; DL = 40H      

MOV AH , 50H  ; AH = 50H

ADD AL , BL      ; AL = AL + BL

ADD CL , DL      ; CL = CL + DL

ADD AL , CL      ; AL = AL + CL

ADD AL , AH     ; AL = AL + AH

MOV DH , AL    ; DH = AL

HLT                    ; EXIT
