The main question about the declaration of the stack segment

Hey, I'm just starting to learn assembly and that’s what I don’t understand ...

In the stack segment declaration, we use something like

     TOS LABEL WORD

I know that TOS belongs to the top of the stack, but does not understand what follows it and what it uses. Help will be appreciated.

What you are doing here is defining a label (stack pointer (SP)) that contains the address of the top of the stack. The label will always contain the address where the last value was clicked.

  • When you invoke the PUSH operation, the contents of the register or memory location is copied onto the stack and the SP decreases.

  • POP, SP (TOS), , , SP .
