Question

I’m using NASM compiler to create small asm applications. I need to load my string on location and I want access it later.
My question is:
Is there any way to store strings in memory and load them later?
Somewhere I have ridden that it’s possible with offset but I don’t know how to use it in NASM.
Can anybody place here links or code for explanation or example? Please help.

Answer 1

Unlike MASM and TASM, NASM does not use offset.

MASM/TASM code:

mov eax, offset MyString
MyString db "Hello World!", 10, 0

or

lea eax, MyString
MyString db "Hello World!", 10, 0

NASM equivalents:

mov eax, MyString
MyString db "Hello World!", 10, 0

or

lea eax, [MyString]
MyString db "Hello World!", 10, 0

Please read NASM documentation.
