Code:
struct PARTICLE                      
  x         dd ?            
  y         dd ?
  dirx  dd ?               
  diry   dd ?
ends

section '.data' redeable writeable
    Sprite      PARTICLE

section '.code' redeable executable

       mov     [Sprite.x], eax
     mov     [Sprite.y], ebx
     ;etc...
     stdcall DrawMySprite, Sprite

proc   DrawMySprite, sprite
     mov     ebx, [sprite]
       mov     eax, [ebx + PARTICLE.x]
