I have declared an structure in asm like this
STRUCT MyStructure
X dd ?
y dd ?
MyStructure ENDS
that's ok, but when i try to acces it as a global variable or a local one the assember trough me errors. For examble we are in a proc called paint
paint proc ;the procudere
local point:MyStructure ;The Structure Declaration
point.X = 3 <--- This line trough an error when i try to acces the
member
paint endp
The Same happens if i try to initialize a global structure:
suppouse:
Strc1 MyStrucutre
the assembler assembles it, but the code again "Strc1.X = 3" is trated as an error.
I have readed carrefully the masm help file.
This is my first stpes in masm and i would like someone help me please.

Forgive me the code is no "Point.X" its "Mov, Point.X" (i make the mistake thinking in C), but the problem is still there.
POINT STRUCT
x DD ?
y DD ?
POINT ENDS
.DATA?
mypt POINT<>
.CODE
PaintFunc PROC
LOCAL pointStr:POINT
mov pointStr.x, 3
mov eax, pointStr.x
...
ret
PaintFunc ENDP
Start:
mov mypt.x, 3
mov edx, mypt.x
....MOV it where? You need to state a destination.
You defined MyStructure.X as a dd, or a word (I forget, thats why I never use 'dd' or 'dw', I use DWORD and WORD and BYTE and...)
Anyway, the point is, MyStructure.X is a memory location, so you can only MOV it to a register. Additionally, the register must be the same size as X is, here a (I think) word.
mov ax, MyStructure.X ; should compile
mov eax, MyStructure.X ; should NOT compile
OK? <g>

Instead of starting a new thread, you should have posted a reply to your original thread, it keeps things nice and organised.....
You said your code still doesn't work, if you post your code (just cut&paste it inline if it is short, not as an attachment), then we can check it.

Thanks for the help, i was so stupid that i have been using "Struct " instead of " Struct".
