hi

i have this code :

OBJETO struct

	x		dd ?

OBJETO ends



.const

MAX          equ 10



.data?

tiros            OBJ MAX dup(<>)



.code

      mov ecx, MAX

      mov esi, offset tiros

      .while ecx

            mov [esi].OBJ.x, ecx

            add esi, sizeof OBJ

            dec ecx

      .endw

the question is...
at the end of the while ill have a ARRAY like this :?:
tiros[10,9,8,7,6,5,4,3,2,1]
how this will work ?

please can anyone help me ? plz ?

thx im a newbie :)

Yes, because SIZEOF(Objet0) is 4 and x is at offset 0.

; counter = 10

 mov ecx, MAX

; esi points to the first element of the array

      mov esi, offset tiros

      .while ecx 

; set x to counter

; this is equivalent to mov [esi][0]

            mov [esi].OBJ.x, ecx 

; point to the next element

; this is equivalent to add esi, 4

            add esi, sizeof OBJ 

; decrement counter

            dec ecx 

      .endw 

its 4 because u defined x as dword - 4 bytes.
