因此，我完成了一个程序，以打印斐波那契数列中的n个数字。但是，某些结果显示为十六进制（如0D）而不是十进制（我希望将其显示为13）。我该如何解决？

.data    
fibon1 db 00h
fibon2 db 01h
fibon3 db ?
msg db "The first 13 numbers of the Fibonacci sequence is",10,13,"$"
n db 11

.code
assume cs:code,ds:data
start:  mov ax,data
        mov ds,ax
        lea dx,msg
        mov ah,09h
        int 21h
        mov bl,fibon1
        call dispnum
        mov dl,' '
        mov ah,02h
        int 21h
        mov bl,fibon2
        CALL DISPNUM
        mov dl,02h
        int 21h
        mov ch,00h

        ret

end start
