you can use

Code:
if arg eq
...
end if    


to determine if some argument passed to macros or not
and optional arguments must be at the end of arguments list

Here's an example:
Code:
macro optional_args name,value {
  name:
  if value eq
    db ?
  else
    db value
  end if
}

optional_args test1     ; => test1: db ?
optional_args test2,15  ; => test2: db 15
optional_args test3     ; => test3: db ?
