when I create the structure like:
Code:

do_nothing struc{

lazy_men_counter dd ?
lazy_woma_counter dd ?
}
    

I can get :

Code:
.data
room do_nothing
.code
mov eax,[room.lazy_men_counte]
    

now eax hold the number of men who do nothing

i C the code may looks like this:
Code:
int a =room.lazy_men_counter;
    

when I want to point the system memory I could not create any structure but just to get the pointer and point the place.
Code:
do_nothing * room;
room=getSystemOperation(); //not real function just set the pointer called 'room'
int a=room->lazy_men_counter;
    


How it could be done in ASM Question

THX

Code:
        virtual at eax ;assuming that eax contains the pointer to the structure
        .nothing   do_nothing
        end     virtual
        mov     eax,[.nothing.lazy_men_counter ] 
    

If I am not wrong.

You can use struct macro from struct.inc file (from both Fasm and Fresh packages):
Code:
do_nothing struc{ 

lazy_men_counter dd ? 
lazy_woma_counter dd ? 
}
struct do_nothing          ; <----------    


and now you can write:
Code:
mov ebx,[eax+do_nothing.lazy_man_counter]

(assuming that eax contains pointer to your structure)    


regards

Hi, still i considering a compiler written in FASM, but,

C#(vs.net, mono) produce il assembly,
if (let me say this again, if) FASM understand il assembly, life is much easier.

May be this?

Code:
  virtual at eax
    eax.do_nothing do_nothing
  end virtual
    


So you can access like this:

Code:
  mov eax,[eax.do_nothing.members]
