The "#" operator can be also used to concatenate two quoted strings into one.
Also conversion of name into a quoted string is possible, with the "`" operator,
which likewise can be used inside the macroinstruction. It convert the name
that follows it into a quoted string - but note, that when it is followed by
a macro argument which is being replaced with value containing more than one
symbol, only the first of them will be converted, as the "`" operator converts
only one symbol that immediately follows it. Here's an example of utilizing
those two features:

    macro label name
     {
        label name
        if ~ used name
          display `name # " is defined but not used.",13,10
        end if
     }    

You're not thinking about something like the '#' operator?

macro _assign_parameters [Param]
{
common
    local ..param_count, ..iParam, ..base_reg
    ..param_count = 0
    if defining_naked = 1
  ..base_reg = esp
    else
        ..base_reg = ebp + 4
    end if
    if ~ Param eq
forward
    ..param_count = ..param_count + 1
    ..iParam = ..param_count * 4 + 4
    if defining_register = 1
      if ..param_count = 1
   Param = eax
      else if ..param_count = 2
      Param = edx
      else if ..param_count = 3
      Param = ecx
      else

      end if
    else
      Param = [..base_reg + ..iParam]
    else
      Param = [..base_reg + ..iParam]
    end if
common
    end if
    param_count.#CurrentClass#.#CurrentMethod = ..param_count
    params.#CurrentClass#.#CurrentMethod equ Param
}
