Print decimal in 8086 emulator

Question

I implemented the multiplication of two big integer in emu8086 with code as below :

; MULTIPLY N1 * N2 = RES
MULTIPLY PROC
    MOV BH, 0H                


        

Answer 1

I solved my problem with changing my code as below :

NORMALIZE PROC
    MOV CH, 0H
    MOV CL, L1
    ADD CL, L2
    DEC CX

    NOMRALIZE_LOOP:
        MOV BX, CX
        DEC BX
        MOV AL, RES[BX]
        MOV AH, 1H
        MUL AH
        AAM            
        MOV RES[BX], AL
        ADD RES[BX-1], AH
    LOOP NOMRALIZE_LOOP
    RET
NORMALIZE ENDP

; MULTIPLY N1 * N2 = RES
MULTIPLY PROC
    MOV CH, 0H
    MOV CL, L1

    MOV AL, '0'

    MOV BH, 0H

    SUB_N1:
        MOV BL, CL 
        DEC BL
        SUB N1[BX], AL
    LOOP SUB_N1

    MOV CL, L2

    SUB_N2:
        MOV BL, CL
        DEC BL
        SUB N2[BX], AL
    LOOP SUB_N2

    MOV CH, 0H
    MOV CL, L1

    MUL_1:
        MOV COUNTER, CL
        MOV CL, L2  

        MUL_2:
            MOV BH, 0H
            MOV BL, COUNTER
            DEC BL
            MOV AL, N1[BX]

            MOV BL, CL
            DEC BL

            MUL N2[BX]

            AAM

            MOV BH, 0H
            MOV BL, COUNTER
            ADD BX, CX
            DEC BX
            DEC BX

            ADD RES[BX], AL
            ADC RES[BX-1], AH
            ADC RES[BX-2], 0H
        LOOP MUL_2     

        MOV CL, COUNTER
    LOOP MUL_1

    RET
MULTIPLY ENDP

I changed the multiplication and storing numbers with AAM function. At the end, i add NORMALIZE function to convert result to decimal. :)

Hope others can use it :)
