EDIT: The example in this post is not correct as Privalov explains in the next post!

As you probably would have guessed, i'm in the process of updating all my macro's from some older fasm versions. And of course I found another oddity...

When doing this:

Code:

macro m var {
 const.#var#.1 equ 1
 match =z,z \{ const.#var#.2 equ 2 \}
}
a equ b
m a

you get: const.a.1 equ 1, const.b.2 equ 2

this because it is evaluated like this:

Code:

const.a.1 equ 1
;const.#a#.2 equ 2
const.b.2 equ 2

In other words, equates are replaced in the match segment when first encountered, and then replaced again, when the segment is actually executed.

Once again, is this intended behavior, and is there a way around it? (i tried escaping (\), but that doesn't work, as the escape isn't executed the first run of course...)

Actually you get "const.a.1 equ 1" and "const.a.2 equ 2" here.

PS. Look into section 2.3.7 to get the information necessary for interpretations.

Sorry, you're right, i interpreted the results wrong...
What i need is a list of macro variables actually...

Code:

macro m var { List equ List,var }
a equ 1
m a

In old versions with fix this resulted in: List fix List,a
Now with all equates this is: List equ List,1 (because equ evaluates equ)

i think there is "define" which doesn't evaluate equates on it's right side, see manual, i'm not sure

That's right, you should use DEFINE:

Code:

macro m var
{
  match list_elements, List \{ define List list_elements,var \}
}

a equ 1
m a

(the MATCH is needed because "define List List,var" wouldn't replace the "List" and thus would be unuseful).
