virtual method is not much convenient:

Code:

virtual at eax
  structure1 STRUCTURE
end virtual

further relocation is not possible as label already defined:

Code:

virtual at ebx
  structure1 STRUCTURE
end virtual

of course we can find out a new name but that is a bit stupid:

Code:

virtual at eax
  structure1a STRUCTURE
end virtual

there are also arrays of structures where base is not fixed and we need a 0-offset of a field, eg:

Code:

struct STRUCTURE
  f1 db ?
  f2 db ?
ends
structure1 STRUCTURE
mov eax,[eax+structure1.f1-structure1]

not the best decision, so that relative offset constants needed ie the macro from a respective *.inc file must be fixed

Code:

mov eax,[eax+structure1.rel.f1] ;etc naming

Just one of the reasons I only use STRUC.
