Code:

struct A
Ba :
  C   dd ?
  D   dd ?
ends

jmp Ba

This, above, compiles.
But what sense can we give it ?
What might be the usefulness of this code ?
(sorry but I dissects fasm to develop next wink)

Code:

C dd ?
D dd ?
...
mov eax,[dw_inst0]
mov ebx,[dw_inst1]
mov [C],eax
mov [D],ebx
...

it can be used for self modifying code. but it doesn't need struct for that.

struct is a high level macro that i never use.
