ex-9.asm(18): what does error A2062: Missing or unreachable CS mean, especially what does A2062 have to do with the error location

What does error A2062: Missing or unreachable CS mean

Roughly it should mean that the CS segment (code segment) is missing or unreachable... Check whether your CS segment is set correctly.

At the very least you should post the source code!
What is the programming environment? Also, what version of MASM is it? If it's a relatively new version, you can consider pseudo-code, then you can skip the segment setup... and it's less error-prone!

The assignment is to count the number of positive numbers, negative numbers, and 0s.

Could one of the experts help analyze what these errors mean? Many thanks

On the first line, it should be "_", not the minus sign "-".
On line 10, it should be assume cs:code,ds:data — you missed a comma.
On line 15, I really don't know why either.
On line 26, it should be begain — you mistyped a letter.
On line 28, it should be int, not inc.

There are too many input errors... just be more careful when writing code.

Thanks very much, I'll pay more attention in the future.

Change line 15 from “cmp [si],0” to “cmp byte ptr [si],0”.
This error only shows up with masm5. MASM6 won't.

As expected, big brother Benshi is amazing...!
