Hi all,
In the below NASM code, I am defining data section without lables.
Code: Select all
SECTION .data
db 0xAB
db 0xCD
db 0xEF
SECTION .text
mov ax, 0xAB
mov ax, 0xCD
mov ax, 0xEF
In the above code I want to access data "0xAB 0xCD 0xEF" from "data segment" in code segment. How to do it?

I think the answer lies in the ill-found assumption in your question.
Use labels.

When you have important data, you should have labels. It makes your code more readable, and easier to write. So why do you want to access this data without labels?

The reason is simple.
1. I want to learn how to aceess those data segment values, without labels.
2. In which case, it is useful to declare such datas without lables.

Accessing the data in the data segment is done by using labels.
Use labels.
