Why it's work?

Code:

macro irp p,[plist]
{
common ..c = 0
reverse
  ..c = ..c+1
  p equ plist
}

macro foo plist
{
local .p
    irp .p,plist    
     display .p+0x30
     restore .p    
     display .p+0x30
     restore .p
     display .p+0x30
}
foo <3,5,9>

and it's can't

Code:

macro irp p,[plist]
{
common ..c = 0
reverse
  ..c = ..c+1
  p equ plist
}

macro foo plist
{
local .p
    irp .p,plist
    repeat ..c
      display .p+0x30
      restore .p
    end repeat
}
foo <3,5,9>

repeat cannot be use to repeat preprocessor directive. use rept instead

"repeat" is one of the control directives, that are processed after the preprocessing is already finished (you can read about it in the manual!). The preprocessor itself does only operations on the text symbols, and - as opposed to assembler - doesn't do any calculations. So you should do it rather this way:

Code:

macro irp p,[plist]
{
  reverse
   p equ plist
}

macro foo [plist]
{
  common
    local .p
    irp .p,plist
  forward
    display .p+0x30
    restore .p
}

foo 3,5,9

Thanks and sorry for my not very accurate question. Embarassed

My tasm program use this macro:

Code:

subm macro plist,subparam
     irp p,<plist>
       sub p,subparam
     endm
endm
.code 
 ...
  subm <[var1],[var2],[var3]>,constant

and i decided to create a such(repeating first param.) for my fasm programs - not like:

Code:

macro subm subparam,[plist]{sub plist,subparam}

I tryed and blocked to the first post example Confused

macro irp work fine, but I dont know how to continue.

Why not like the "subm" sample? It does exactly what you need.
What you request looks, however, like the recently discussed FOR directive: http://board.flatassembler.net/topic.php?t=3823&postdays=0&postorder=asc&start=25#28033
(IRP was an old name for FOR in MASM).

I find a solution for my problem. It was under my eays.

Code:

macro subp subparam,[params]
{sub params,subparam}

macro subm params,subparam
{subp subparam,params}
.code 
... 
 subm <eax,ebx,ecx>,edx
...

will be compile

Code:

sub eax,edx
sub ebx,edx
sub ecx,edx

To make it better - must checking params for it's type, equates and nonsenses.
Thanks again

Oh, that was what was troubling you - I'm sorry, I did not understand what really your problem was. And you wanted just to convert the single parameter into multiple parameters (exactly what your solution does).

Anyway, I have just implemented the IRP in fasm, check out the 1.63.5 release when I upload it.
