求汇编代码

要求：检查9*9 乘法表内数据是否正确，将不正确位置确定下来并显示在屏幕上；
如数据部分：
data segment
table db 7,2,3,4,5,6,7,8,9 ;9*9 表数据
db 2,4,7,8,10,12,14,16,18
db 3,6,9,12,15,18,21,24,27
db 4,8,12,16,7,24,28,32,36
db 5,10,15,20,25,30,35,40,45
db 6,12,18,24,30,7,42,48,54
db 7,14,21,28,35,42,49,56,63
db 8,16,24,32,40,48,56,7,72
db 9,18,27,36,45,54,63,72,81
……
data ends

检查结果：
x y
1 1 error
2 3 error
4 5 error
6 6 error
8 8 error

急！请各位帮忙
请问按照此代码，LINK时为什么会出现no stack segment

有点乱，你看看吧
data segment
table db 7,2,3,4,5,6,7,8,9 ;9*9 表数据
db 2,4,7,8,10,12,14,16,18
db 3,6,9,12,15,18,21,24,27
db 4,8,12,16,7,24,28,32,36
db 5,10,15,20,25,30,35,40,45
db 6,12,18,24,30,7,42,48,54
db 7,14,21,28,35,42,49,56,63
db 8,16,24,32,40,48,56,7,72
db 9,18,27,36,45,54,63,72,81
errmsg db ?,20h,?,'error',0ah,0dh,'$'
