Hellow, I got some questions about asm I would love being answered:

* Can I think of registers - eax,edx etc as variables predefined as integers in the code?

* Why is the code in memory view in asm? Could it be in something else? that just shows how the machine code handles it, what I am saying is that the asm code in memory view is like a translation for the machine code the program uses in its memory?

* a pointer is pointing to an adress and holds a value, but it doesnt have to hold a value for that adress, am I right?

I could eventually make a asm tutorial when I get hold on how asm works more indepth thus supplying you with a reason for answering me these questions

thanks ALOT x0r for the answers

There are only three all purpose registers (eax, ecx, edx). You should not modify ebp, esp, or eip. ebx, esi, and edi can be used as all purpose but after using them, you should always return them to their original values.

No, ebx isn't used anymore, so the GP registers are

how do you define a pointer in asm? //thanks for all the answers guys!

[samuri25404]

I'm a bit rusty, but try this:

[Symbol]

Pointer = [Base Address Value] + Offset = Destination; (Address it points to)
lea eax,[ecx+20] will just store ecx+20 in eax.

[rump]

so its a bit of a bridge between 2 adresses then? adress1+offset --> adress2
therefor adress1 is adress2 minus the offset?

[Symbol]

No, the value of address1 is address2-offset.
Lets say the address 10 holds the value 3, so the pointer 3 + 4 will point to the address 7.
