Code:

virtual at UserNameDrop+4000
        GDT_limit dw ?
        GDT_address dd ?
        GDT_proc dq 0
    end virtual 
mov eax,[GDT_address]
mov eax,[GDT_address+sizeof.nxtElement] ;how get size virtual at UserNameDrop+4000 ?

I know the virtual at UserNameDrop+4000 size 10 bytes.
but how get this size from virtual at UserNameDrop+4000 ?

I found this variant.

Code:

virtual at UserNameDrop+4000
    @@:  GDT_limit dw ?
         GDT_address dd ?
         GDT_proc dq 0
         sizeVrt = $ - @b
    end virtual
    mov [GDT_address],11
    mov [GDT_address+sizeVrt],11
