How to redefine an area having only the pointer to the area?

[dedndave]

if it's my own structure, i find a different way to do it - lol
if it's defined by MS, i have to work with it   :P

In this case you have to. :t

One more question about data and PROC

If I have 3 equates on main prog, and I call an external PROC
in a LIB, that uses these equates, how should I define them
in order to make them visible and usable by both main and proc?

Code Select Expand


One  EQU 1
Maxrow EQU 32
MaxCol EQU 128
....
CALL AnyProc


Code Select Expand


AnyProc PROC

?????

mov eax, Zero
mov ebx, MaxRow
mov ecx, MaxCol
.....

equates don't have "visibility" like data, per se
you can define the same equates in the program source, and in the source for the module
it's nice if they are the same value   :P

another way to go is to put the common equates in an INC file
then, include that INC file in both sources

remember, at assembly time, equates are resolved as simple numeric constants
you might have a hard time with referencing a symbol like this from 2 different files

END_DATA EQU $

Something a little bit obscure is the mixed use of STRUCT and
defined data that MichaelW does in its last example:

Code Select Expand

    printf("|%s|\n\n", ADDR Area_)
Considering you have never addressed Area_ in your code
and it is initialized to spaces, what did you expect the prog
should display with the previous line of code?

It displays the initialized structure as an ANSI string, which I thought was what you were after. I added the vertical bar characters before and after the string so you could see where it started and ended.

Thanks Dave and Michael.
I think I can go on until next doubt.  :P
