Hi. I need to define a huge amount of labels of different types. I used a simple macro below but it doesn’t work with structs. Is there any way to define Bar as Xyzzy structure using such macro?

Code:

        format  binary
        include 'win32a.inc'

struct Xyzzy
 n dd ?
ends

macro def name*,addr*,type*
{
  if type eqtype 0
    label name at addr
  else if type eqtype byte
    label name type at addr
  elseif `type eq 'code'
    label name at addr
  else
    virtual at addr
      name type
    end virtual
  end if
}

def Foo,0x123456,dword
def Bar,0xabcdef,Xyzzy

Edit: correct macro:

Code:

macro def name*,addr*,type*
{
  if ~defined(sizeof.#type) & (type eqtype 0)
    label name at addr
  else if (type eqtype byte)
    label name type at addr
  else if `type eq 'code'
    label name at addr
  else
    virtual at addr
      name type
    end virtual
  end if
}

No ideas? Is it impossible?

Your "if type eqtype 0" becomes "if Xyzzy eqtype 0" and is interpreted by preprocessor as a definition of Xyzzy structure with "if" name. To avoid this, you can rearrange the condition, or do it like:

Code:

  if (type eqtype 0)

Ashamed. Thank you. It works with this condition:

Code:

if ~defined(sizeof.#type) & (type eqtype 0)
