ok , i got it.

Hi all ,

may any one explain the next macro , i have tried to got it but .....

Code:

macro x86.parse_operand_value ns,op             local buffer,is_name,auto_extrn            define buffer op:             while 1                     match sym tail, buffer                             define buffer tail                             load is_name:1 from Name_XLAT:`sym and 0FFh                             if is_name                                    if defined auto_extrn.sym & (auto_extrn.sym | ~ defined sym)                                           extrn sym                                            auto_extrn.sym := 1                                   else if ~ defined sym                                            auto_extrn.sym := 0                                   end if                            end if                     else                             break                     end match             end while             x86.parse_operand_value ns,op     end macro

So
1- what this line means

Code:

define buffer op:

2- what is the "sym" here and where it declared

Code:

match sym tail, buffer        load is_name:1 from Name_XLAT:`sym and 0FFh

3- also if each lined commented so that i can got it.

excuse my newbee.

thanks for any help.

1 > "buffer" is defined as "op" with a colon (:) appended.

2 > match will define "sym" as the first symbol from "buffer", and "tail" as the all of the remaining symbols from "buffer"

3 > Not sure what you question is here?

thanks you

may you kindly explain each line in the macro !!

As I mentioned earlier, this macro is especially tricky. I'd suggest you first take some time to get accustomed with the simpler ones, including the operation of MATCH. You can start with reading the section on MATCH in the manual and then the increasingly complex examples in my introduction to fasmg.

any way i have deleted my last two posts ,

thank you all for your help.

Code: ... preprocess macro invoke name,args&         iterate arg,args                 indx %%-%+1                 push arg         end iterate         call [name] end macro invoke  MessageBoxA,0,_message,_caption,0 The output looks like: Code: push 0 push _caption push _message push 0 call [MessageBoxA]

Is there any way to catch this lines in macro to output:

Code:

invoke  MessageBoxA,0,_message,_caption,0 ;iterate arg,0,_message,_caption,0 ;this ;indx 4-1+1 ;and this push 0 ;end iterate ;and this ;indx 4-2+1 ;and this push _caption ;end iterate ;and this ... ; ...

I mean how to catch them not in time of macro definition but in time params go throw macro?

I tryed to play

Code:

macro preprocess         local Preprocessor         macro gate list&                 iterate instr, list                         macro Preprocessor.instr?! args&                           ;db `instr `args                                 esc instr args                         end macro                 end iterate         end macro          gate end,macro,iterate,indx,irp,irpv,repeat,rept,while,break,if,else,match,rmatch,rawmatch,include,postpone,namespace,display         macro make_interceptor instr                 struc (label) ? decl&                         instr `label,' ',`decl,13,10                 end struc         end macro          make_interceptor db;display         namespace Preprocessor         postpone                 end namespace          end postpone end macro preprocess;launch CMD line '"%SystemRoot%\system32\notepad.exe" "%OUTPUT%"' macro ?! args&   line `args,args   args end macro macro invoke name,args&         iterate arg,args                  indx %%-%+1                  push arg          end iterate          call [name]  end macro invoke  MessageBoxA,0,_message,_caption,0

and output

Code:

line '', line '', line '', line 'macro invoke name,args&',macro invoke name,args& line '', line 'invoke MessageBoxA,0,_message,_caption,0',invoke MessageBoxA,0,_message,_caption,0 line 'iterate arg,args',iterate arg,0,_message,_caption,0 line 'indx %%-%+1',indx 4-1+1 line 'push arg',push 0 push 0 line 'end iterate',end iterate line 'indx %%-%+1',indx 4-2+1 line 'push arg',push _caption push _caption line 'end iterate',end iterate line 'indx %%-%+1',indx 4-3+1 line 'push arg',push _message push _message line 'end iterate',end iterate line 'indx %%-%+1',indx 4-4+1 line 'push arg',push 0 push 0 line 'end iterate',end iterate line 'call [name]',call [MessageBoxA] call [MessageBoxA] line 'end macro',end macro line 'end namespace',end namespace line 'end postpone',end postpone

insted of word "line" I wished ";" and instead of blank lines skip them

You'd need to modify the way in which macros are defined. Possible, but not easy.
