Assembly 在程序集中创建记录

在工作了几个小时后，我完成了程序，它将记录作为输入，计算总数和平均数，并将其存储在记录中

Records    DW    01, 12, 60, 54, 57, 00, 00         
        DW    02, 11, 70, 67, 77, 00, 00
        DW    03, 11, 55, 60, 65, 00, 00 
        DW    04, 12, 75, 66, 83, 00, 00
        DW    05, 12, 49, 59, 69, 00, 00    
;field 1: roll, field 2: age, field 3-5: marks, field 6: total, field 7: average

这是我的密码

但我在这里面临的问题是，尽管它需要用户的输入，它没有将其存储在记录中我很想知道我在哪里犯了错误。

不确定您的问题是什么，但最后的

ret4

看起来非常可疑，因为您没有传递任何参数。一个真正好的开始是更好地记录您的子程序。他们把参数放在什么寄存器中，把返回值放在哪里，修改什么寄存器或内存？这是一大堆需要排序的代码。你能把你的问题降到最低限度吗？
