macro1 is 'push'
macro2 is '$invoke'
macro1 use macro2, macro2 use macro1.
So it doesn't work. macro1 doesn't calls in second time.
if I in macro2 purge macro1 and then define macro1 all works. But It is too slow. What can I do?(I can show code it hard to understand me).

Example.

Code:

format PE GUI 4.0

include "C:\fasm\INCLUDE\WIN32AX.INC";standart macro + standart include

macro m1 vl1,w
{
        display "enter the macros m1",13,10
        if w = 5
                push vl1
        else
                m2 vl1
        end if
}
macro m2 vl1
{
        display "enter the macros m2",13,10
        m1 vl1,5
}




.code
__EntryPoint:
        m1 eax,0
        ret
.end __EntryPoint

defining macro1 again in macro2 is only way to do it. And what makes you think it is slow?

btw, you don't need to purge it there... it is no more defined.

how can i know that macro is defined?
like "ifndef"?
if push ` defined
include "push.inc"
end if

There is no way to know it and it is intended.
The macros in fasm are stacking, that is the new macro when uses the same name inside of itself, uses the previous version of that instruction/macro. So you can redefine macros like in this classic fasm's sample:

Code:

macro mov arg1,arg2,arg3
{ if arg3 eq 
   mov arg1,arg2
  else
   mov arg2,arg3
   mov arg1,arg2
  end if }

where "mov" inside the macro is the original MOV instruction, but it can also be some previous "mov" macro that extended the syntax in different way.

For this reason the only way to do a macro recursion in fasm is that constructor-macro technique.
