我的这个测试通过了，但是就最后三轮循环被除数写入不正确，也不知道什么原因，求高手解答！（我怎么想都想不通，前18次循环都正常）：

用你的程序后三轮执行结果：
被除数位置 除数 商
1409:0200 31 39 39 33 20 28 44 39-00 20 5E 38 20 04 01 20 1993 (D9. ^8 ..
1409:0210 31 39 39 34 20 28 F0 46-00 20 99 3B 20 30 01 20 1994 (.F. .; 0.
1409:0220 31 39 39 35 20 08 24 5B-00 20 88 45 20 4F 01 20 1995 .$[. .E O.
00394428H = 3753000
0046F028H = 4649000
005B2408H = 5973000
在我这边用你的程序结果都对。
有瑕疵的地方是程序di没有赋初值，给dx赋初值0有点多余，但这都不影响程序执行结果。 | | |
