[fasmg] Symbol is undefined or out of scope problem

Tomasz, please take a look at the small template below

Code:

macro datatypes types*&
  irp <n, type>, types
    macro type args:[?]&
      match [?], args
        emit n: ?
      else match [x], args
        emit n: x dup ?
      else match [x] value, args
        match =, v, value
          emit n: x dup ?, v
        else
          emit n: x dup value
        end match
      else
        irp arg, args
          if arg eqtype ''
            emit n: arg
          else
            local value
            value = +arg
            emit n: value
          end if
        end irp
      end match
      type.__size = n
      datatype.type equ ::type::
    end macro
    struc (name) type args&
      label .: n
      type args
      name.__size = n
      name.__length = $ - .
    end struc
  end irp
end macro

datatypes 1,byte?, 2,word?, 4,dword?, 6,fword?, 8,qword?, 10,tbyte?, 16,oword?

macro log.number num
  local n, s
  n = +num
  if n = 0
    s = '0'
  else
    s = 0
    while n > 0
      s = s shl 8 + (n mod 10 + '0')
      n = n / 10
    end while
  end if
  display string s,13,10
end macro

;------------ ^^ just helpers above to compile --------------

macro struct? structname
  macro end?.struct?!
      end namespace
      irp arg, args
        match p:v, arg
          log.number .p.__size
        end match
      end irp
    end struc
    virtual at 0
      structname structname
      structname.__size = $
    end virtual
    purge end?.struct?
  end macro
    struc (name) structname args&
      label .: structname.__size
      namespace .
      name.__size = structname.__size ;<<<<<<< problem line
end macro

struct POINT
  x word
  y byte
end struct

struct POINT2
  z POINT
end struct

my POINT2 z.x:1, z:1

I'm trying to get the size of a variable defined as structure. Variable, not structure itself, because later it will be an array of structures.

The problem is when I add

Code:

name.__size = structname.__size

I start getting the following error:

Quote:

Processed: label .: POINT.__size
Error: symbol '__size' is undefined or out of scope.

However, both sizes are logged correctly. If line is removed, label .: POINT.__size doesn't generate the error any more.

I thought that it could be processing order, and structname.__size is not initialized yet, when name.__size appears in code, but I guess it would then fail on that very line. Thanks in advance for your assistance!
