The macro "struct" will initialise the sizeof field.

But make sure you use the dot (.)

Code:

...
mov eax,sizeof.RECT
...

depends on how you declare structure. If you use builtin "struc", then you can declare it by hand:

Code:

struc MYSTR
{
.a dd ?
.b dd ?
}
virtual at 0
  MYSTR MYSTR
  sizeof.MYSTR:
end virtual

if you use struct macro, then it declares "sizeof." automatically, as revolution told.
