Code:

macro xcod {
                dd X
                restore X              
                 }  

section '.code' code readable writeable executable
start:  X EQU 1
         X EQU 2
         X EQU 4 
         X EQU 5

section '.data' readable writeable
         xcod

I want get in section '.data' all X. And X EQUATES there may be many (1 or 2000 X EQUATES ) !
The result in section '.data' should be a:
dd 1
dd 2
dd 4
dd 5

How to do it ?

I have to use this macro ? Am I right?
macro list_builder name {
local m,c ;avoid name clashing
c equ 0 ;initialise the counter
macro .#name [a] \{
\common
rept 1 x:c+1 \\{
c equ x ;update the counter
macro m\\#x a ;open the macro
\\}
\}
macro name#_list \{
rept c x \\{
m\\#x ;replay each line
\\}
\}
}
list_builder list2

All except for the last line which is not part of the macro.

Funny coincidence (?), but it looks like the new directive that I was considering recently (after reading the other thread) would fit perfectly here. I thought I could implement an IRPV directive that would allow to iterate through all the past values of a symbolic variable. I'm still not sure whether it would really be useful enough to justify such an addition to language.

This can be useful in 3d games !!!
I seriously !

If user create texture ( interface ID3D11Texture2D = 4 bytes in data), macro put all textures in data.

DataBgn:
put all textures
DataEnd:

When we go out of the game, DX11 release all textures from DataBgn to
DataEnd.
We got the automatic creation and deletion textures for Directx 11 !!!
Do not need hands to write every texture in date !!! Its very good !
