请问如何把16进制数转化为10进制数显示输出？谢谢！
--------------------------------------------------------------------------------
16进制数在内存INPUT处，使用大写字母，结果在OUTPUT中
最大为双字
大致如下：
input db "23AF ",0
w1 dw 1
w2 dw 0
output db 20 dup(0)
xor ax,ax
mov si,offset input
call h_to_b
mov di,offset output
mov cx,10
call b_to_d
xor ax,ax
stosb
h_to_b:
lodsb
push ax
or ax,ax
jz b03
call h_to_b
pop cx
cmp cl, "9 "
ja b01
sub cx, "0 "
jmp b02
b01:sub cx, "A "
b02:mov ax,w2
mul cx
mov w2,ax
mov ax,w1
mul cx
mov w1,ax
add w2,dx
b03:ret
b_to_d:
mov ax,w2
xor dx,dx
div cx
mov w2,dx
mov dx,ax
mov ax,w1
div cx
mov w1,ax
or ax,dx
jz w11
push dx
call b_to_d
pop ax
add ax,030h
stosb
w11:
ret
