Hi, Privalov:
Can you extend the "#" syntax to contatenate one symbol and "%" into one? Please see the below macro, It will help to implement that supported variable pararmeter on proc macro.

Code:

macro varg_parse num,arg
{
        repeat  num
         arg#.#% equ     arg+%*2
     end repeat              
}

arg   equ     bp
  varg_parse      2,arg
       
    mov     ax,[arg.1]
  mov     bx,[arg.2]

Thank you.

The # operator works at preprocessor stage, when % symbols doesn't mean anything special. It is the assembly stage when % has assigned some special value (in the same way as $ symbol). The whole preprocessor is text-substitution-based only, there are no expression calculation or enumerating mechanism in the preprocessor.
