sorry for the easy question but i don't generally use preprocessor for anything, but for defining the size of data i do:

Code:

macro sddata_start {
    struc db [data] \{
        \common
        . db data
        size.\#. = $-.
    \}

    struc dw [data] \{
        \common
        . dw data
        size.\#. = $-.
    \}

    struc rb size \{
        \common
        . rb size
        size.\#. = $-.
    \}

    struc rw size \{
        \common
        . rw size
        size.\#. = $-.
    \}
}
;---

macro sddata_end {
    restruc db
    restruc dw
    restruc rb
    restruc rw
}
;---

but because i use '_' in string name convention it looks a bit ugly imo

Code:

mov ecx, size._string

i would prefer

Code:

mov ecx, _string.size

but if i do:

Code:

.\#.size = $-.

'_name.size' doesnt get defined

solution?

Use just:

Code:

.size=$-.

instead.

ah, i feel like a moron, i figured fasm would read the '.' as a period itself and define '.size' literally, Embarassed

, perhaps i should have refered to the manual
