According to the post using types defined with EQU in structures
i update the typedef macro and work OK.

Code:
macro macro@typedef base,[type] 
{ 
    forward
    struc type [v] 
    \{ 
        \common match any, v \\{ . base v \\} 
            match , v \\{ . base ? \\}
    \} 
    macro type [v] 
    \{ 
        \common match any, v \\{ base v \\} 
            match , v \\{ base ? \\}
    \}
    virtual at 0
      base ?
      sizeof.#type=$
    end virtual
} 

macro typedef [statement] 
{ 
    common
    match gs@base gs@type,statement
    \{
        macro@typedef gs@base,gs@type
    \}
}
    


for example:
Code:
typedef dd SDWORD
typedef SDWORD DWORD,INT32,LONG
typedef db CHAR,BYTE

_WIN64 equ FALSE

match =TRUE ,_WIN64{typedef dq PVOID}
match =FALSE,_WIN64{typedef dd PVOID} 

typedef PVOID HANDLE,PSTR,PWSTR
;....................
;struct define
struc point x,y
{
  .:
  .x SDWORD x
  .y INT32 y
  .size = $ - .
}

struct SIZE
  cx LONG
  cy LONG
ends

typedef SIZE newSIZE
;....................
;Data define

m1 SDWORD 12,13,14,sizeof.DWORD
m2 INT32 12,13,14,sizeof.INT32
my point 7,my.size

INT32
m3 INT32 
;....................
;local define

proc WindowProc uses ebx esi edi,hwnd,wmsg,wparam,lparam
    local hDC:HANDLE
    local mySize:newSIZE
    ...
    


Typical windows data types:
Code:
_WIN64  equ FALSE    ;(or TRUE)

typedef db  UINT8 ,INT8 ,BYTE ,CHAR,UCHAR
typedef dw  UINT16,INT16,WORD ,WCHAR
typedef dd  UINT32,INT32,DWORD,LONG,ULONG
typedef dq  UINT64,INT64,QWORD,LONGLONG,ULONGLONG

typedef DWORD BOOL,long,int,HRESULT

match =TRUE ,_WIN64{typedef dq PVOID}
match =FALSE,_WIN64{typedef dd PVOID} 

typedef PVOID HANDLE,PSTR,PWSTR,LPVOID

That's a simple and concise feature, so don't make it more complicated, than it should be. Wink
Code:
macro macro@typedef base,[type]  
{  
    forward 
        struc type [v=?] \{ \common . base v \}
        macro type [v=?] \{ \common base v \}
        virtual at 0 
            base ? 
            sizeof.#type=$ 
        end virtual 
}    

Btw. I'd rather prefer a single macro, i.e. no multiplication of entities beyond necessity:
Code:
macro typedef [statement*]
{
    common match gs@base gs@type,statement
    \{
        irp type,gs@type
        \\{
            struc type [v=?] \\\{ \\\common . gs@base v \\\}
            macro type [v=?] \\\{ \\\common gs@base v \\\}
            virtual at 0
                gs@base ?
                sizeof.\\#type=$
            end virtual
        \\}
    \}
}

aha,I_inc, I appreciate your macro. ^_^ But [v=?] is new feature.

version 1.70 (Apr 17, 2012):
[+] Macroinstruction argument now can have default value, defined with "="
symbol followed by value after the argument name in definition.
------------------
The top macro is also applicable to version 1.67 and above.

Sure, you are right. But considering, that fasm is small, free, portable and retains backward compatibility, I see no reason to support older versions by introducing more complexity. IMHO older versions support is only eligible if no trade off is needed to achieve that.
