Would anyone know how to modify the struct macro to align structures on any boundry? An example of what I want to do is below. The align command doesn't work inside a struct macro. I get an 'out of memory error' with the macro code shown in the last code block of this post, does anyone else?

Code:

struct D3DXVECTOR4:16 ;alignment is 16 bytes specified by ":16"
     x dd ?
     y dd ?
     z dd ?
     w dd ?
ends

Code:

struct D3DXVECTOR4 ;make the align command work in struct macros
align 16
     x dd ?
     y dd ?
     z dd ?
     w dd ?
ends

Macro bug?

Code:

struct _alignD3DXVECTOR4
       x dd ?
       y dd ?
       z dd ?
       w dd ?
ends

macro astruct structname {
      align 16
      struct structname
}

section '.data' data readable writeable
  astruct _alignD3DXVECTOR4

madmatt:

1) align is "directive" not command
2) there is nothing like "align doesn't work in struc". "Struc" is preprocess time thing (textual substitution), and "align" is later assembly time thing.

but you are right there still is a problem. That's why i use struc not struct -> i know how it works Wink

Does anyone know how to get around this? Confused

I'd like to have this feature so I wouldn't have to remember each time I use a stucture that works better with alignment.
