Amount of output so far ?

Hi folks,

After years of silence, I'm back to fasm and it still rocks.

I'm trying to write an MBR so I need my code to relocate itself before loading the bootsector of the active partition.
Basically, I'd like to do it by having the following layout :

Code:

format binary
use16

org A
; copy MBR to whatever
; jmp to whatever:B

org B
; chainload

As it works well, what I'd like to ask is more a feature request : as I need to pad my code until offset 0x1be (from the beginning of the file, this is where the partition table is to be located), I need to define labels at the beginning and end of the first part (because $$ refers to the second org), so that I can pad with

Code:

times 0x1be - ($ - $$) - (A.end - A.start) db 0

Basically, I'd like to write something like

Code:

times 0x1be - ($$$) db 0

With $$$ (or whatever) being the number of bytes written to output so far, in all address spaces.

How hard would it be to add such a special value ?
And if it's easy, could it be considered for inclusion in fasm ?

Thanks a lot.

format binary use16 _$$ = 0 _$ equ (_$$+$-$$) macro org address { _$$ = _$ org address } org A ; copy MBR to whatever ; jmp to whatever:B org B ; chainload times 0x1be - _$ db 0
