As a kind of newbie in Assembler, I searched for tutorials. I only found two of them, but nothing was said about how to declare or define variables.
I'm quite sure there's somebody how knows how to do.

Thank you

All a variable is, is a memory location where you store data. So assuming you want to store a DWORD (4 byte value), you would have:

my_variable dd 0

(or similar) somewhere in your data segment (or code segment if that is writeable in your application).

Then to load it into EAX, for example,
mov eax, [my_variable]

Do something:
inc eax
mov [my_variable], eax ; save it
