I am working on a text based tic-tac-toe game for some users, using x86 assembly on an Intel Core i7 12700K systems running Ubuntu 22.04. I’m using NASM assembler and GNU Linker for development.
I am beginning to have an issue with the `change_player` function. The code attempts to toggle the player variable between “0” and “1” using XOR, **but the value remains unchanged**.
What is causing the player variable to not be modified as expected?
Are there any issues with memory access or data manipulation in the change_player function?
What are the recommended approaches for managing player turns please ?

I have edited the code adding and committed it , but strangely, I’ve found out that the `change_player` label isn’t changing anything, in fact it looks like that my entire code is not modifying the variables of the section data.
“`
change_player:
mov si, player
xor byte[si], 1
ret “`
Does not change the variable player, the value is always **0**
