Fasmw 1.73
Code:
Ignor_flg = 1
rept Ignor_flg { some code or some macros }
...some code
MacroA ;calculating some values and changed Ignor_flg to 0 or 1
            ;now I want ignoring rept if macroA set Ignor_flg = 0

Code:
Ignor_flg equ 1    
But that won't work due to the single pass preprocessor.

Put a if/end if inside the macro.

Its work if I do first macroA set Ignor_flg equ 1
Than do second macroB check if Ignor_flg = 1

I want different way.
Code:
MacroB
Some code
MacroA

Use equ for preprocessor stage. Can't be forward referenced.

Use = for assembler stage. Can be forward referenced, but only for a single assignment. IF you have multiple assignments then you can't forward reference.

Hm.
Did I can write my new pass(after preprocessor stage) in fasm source code ?
And how hard implemented it to fasm ?

Use only a single assignment.
Code:
;Ignor_flg = 0 ; <--- don't put an assignment here!
rept { ; <--- are you sure you want rept? "if" by itself should be fine.
 if ~ Ignor_flg
  ;...
 end if
}
;...
Ignor_flg = 1 ;  <---use only one assignment
;Ignor_flg = 0 ; <--- don't put a second assignment here!

Code:
macro mcAA p {
if p = 1
Ignor_flg1 = p
end if
}
 
            if ~defined Ignor_flg1
               inc ebp
               display 'uuu;;'
            end if
...some code
            mcAA 0 ;0=do inc ebp.  1=not do inc ebp
