汇编题目:数字转字符,并在窗口上显示出来

程序题目:将数字以十进制的形式显示在屏幕上

assume cs:codesg

data segment
db 16 dup(0)
dw 123,12666,4,8,79
data ends

stack segment
db 100 dup(0)
stack ends

codesg segment
start:mov ax,data
mov ds,ax
mov ax,stack
mov ss,ax
mov sp,100
mov cx,5
mov bx,0
mov ax,800h
mov es,ax

mov ax,ds:[16+bx]

;si表示数据首地址,di表示数据首地址的偏移,
;dh表示行,dl表示列,
showStr:

xor ax,ax
mov al,dl
mov bl,2

;push al    ;列

mov al,0ech
showRead:

mov es:[bx+di],cl

mov es:[bx+di],al
inc si
inc di
jmp showRead
back:
pop si
pop ds
pop es
pop dx
pop cx
pop bx
pop ax

codesg ends
end start


以上程序为自己编写,由于刚学汇编,所以可能会有很多错误,希望你能指正,大神!!!
