Hi everyone,
I have some questions about the macro definitions in the previous post, I'm used to the "old fashioned" way of programming in assembler and would like to learn to use a more organized way, and the new structure macros may be it. I would like to ask a few questions about the struct macros.

Question 1
How would access the x member of point of the structure WINDOWPLACEMENT?
like this?: mov eax,ptMinPosition.x OR mov eax,rcNormalPosition.left

struct POINT
DWORD x
DWORD y
ends

struct RECT
DWORD left
DWORD top
DWORD right
DWORD bottom
ends

struct WINDOWPLACEMENT
DWORD length
DWORD flags
DWORD showCmd
POINT ptMinPosition
POINT ptMaxPosition
RECT rcNormalPosition
ends

--------------------------------------------------------
Question 2:
How would I define an array of many dwords (or any other data type) in the structure definition?

struct MYSTUCTURE
DWORD data1
WORD data2
like this?: BYTE mystring times 80 db 0
like this?: BYTE mystring <times 80 db 0>.
ends
--------------------------------------------------------
Question 3:
How about a POINTER data type for various kinds of data
like this:

struct MYSTRUCTURE
TPTRZ arrayofchar ; pointer to array of characters (text,zero terminated)
DPTR arrayofdwords ; pointer to array of dwords
PPTR arrayofpointers ; pointer to array of pointers
ends

Now TPTR,DPTR,PPTR would all be dword size, unless you are programming for the AMD64 processor! in which they would be all
qword size!!

HEY PRIVALOV!, you are doing an excellent job on this assembler! When do you sleep? You deserve a vacation!

Answer 1:
First, MOV's in fasm are like those in debug; mov eax, 0x12345678 loads an immediate, mov eax, [0x12345678] loads the dword stored at address 0x12345678

If you defined MyInstance WINDOWPLACEMENT

You can load eax with the address of x for MyInstance with:
mov eax, MyInstance.ptMinPosition.x

Or to load eax with the value of x use:
mov eax, [MyInstance.ptMinPosition.x]

Answer 2:
Look at my post for SZ in http://board.flatassembler.net/topic.php?t=273

Answer 3:
I think the following will work:
TPTRZ equ DWORD
DPTR equ DWORD
PPTR equ DWORD

Thanks eet_1024, Here is a c example of something that I want to do.

struct gfxinfo {
unsigned word vendorid1
unsigned word vendorid2
char vendorname[40]
}

struct gfxinfo mygfxinfo = {0abcdh,0deffh,"Matrox Millenium Mystique 220"}

Is there a way to do this with the structure macros in the previous post?

For this purpose it's better to use the "native" struc, like:

Ok everyone, thanks for your help , I'll give all the solutions a try.
Take Care,
Matt
