Code:

struc _struct
{
.x dw ?
.y dw ?
.sizeof = $ - .
}



virtual at bx

_ms _struct

end virtual



mov ax, [_ms.sizeof]

    

I need to know how large is structure. How do i do it?

btw, what common/forward/reverse do to structure?

You need to define the _ms label:
Code:
struc _struct
{
     .:
      .x dw ?
     .y dw ?
     .sizeof = $ - .
}

ok, but in example is:

struc db [data]
{
common
. db data
.size = $ - .
}

ah ok, its a declatarion along with assignment, equal to .:, db data, .size.

thx.


is there any use for reverse/common/forward in struct? I know how to use it in macro, but in struct? I dont see the point.
