How to do it ?
See the code and results in attachment.
Regards, Rockphorr.
I believe you may have invoked the Macro Master's name.
JJ should be along shortly.
There is no variable declaration, then offset will not work (like error say).
For example:
.data
Mysome Some {0,0,0,0}

Post complete working code please. May be it is impossible to write code doing this.
What's the problem? It seems to work:
*** Assemble, link and run VALUE_ASM ***
*** Assemble using UAsm64 ***
@V_size = 8h
@V_ofs = 4h
Tmp_File.asm(31) : Error A2099: END directive required at end of fileQuote from: Rockphorr on June 09, 2024, 06:15:17 AMPost complete working code please.
Normally, I agree. But here OP just wants the echos - and they work.
The CodeSize macro (https://www.jj2007.eu/MasmBasicQuickReference.htm#Mb1221) works in a similar fashion.

I use ml of masm32 from masm32.com instead your UAsm64
:biggrin: it's a lot more simple that your idea:

ups, it was my fault,
Your code works fine!
Thanx!!!

UAsm is a Masm32 clone, 100% compatible. And at least a factor 3 faster.

Couse this obj has no code inside. Link did not find any label of code.
Yes, exactly.
I didn't mean to bring this up to further muddy the waters.
So did you get everything to work OK?
Quote from: NoCforMe on June 09, 2024, 09:05:35 AMSo did you get everything to work OK?
Maybe I am a little
slow, but I don't understand what this piece of code is actually supposed to
do... :undecided:
As is, it seems not very useful as a program since the object file has no code. Am I missing some key point to this?
Maybe it would be more useful to show an example of how/where it would be used.
He's trying show offsets into a structure for its members (hence the echo). That's all.

It just seemed weird to me. So, I had to ask.
Well, it might have been kinda a dumb question.
But the say the really dumb question is the one you don't ask.

All your questions are fine. I think that most of masm directive should generate more information.
For example, proc should generate proto to output inc_file.
I make this macro to avoid sharing full structure in module, instead i use this macro to create const definition.
value.asm

end
ml value.asm >log.txt
Copy from log.txt to some.inc following line and use it in another module.
some.inc
@V_ofs = 4h
Not every assembly-language program need generate any code at all.
Here's a tool I wrote to tell me which constants were not defined in our own windows.inc:
;====================================================
;NotInWindowsInc.asm
;
; Tool to go through a list of symbolic constants and output
; those which are NOT defined in MASM32's windows.inc.
;====================================================
.nolist
include \masm32\include\masm32rt.inc
.list
$ce macro arg1, arg2
ifndef &arg1
% echo &arg1 EQU &arg2
endif
endm
echo Constants NOT defined in MASM32 include files:
$ce IMAGE_FILE_MACHINE_UNKNOWN, 0
$ce IMAGE_FILE_MACHINE_AM33, 1d3H
$ce IMAGE_FILE_MACHINE_AMD64, 8664H
$ce IMAGE_FILE_MACHINE_ARM, 1c0H
$ce IMAGE_FILE_MACHINE_ARMNT, 1c4H
$ce IMAGE_FILE_MACHINE_EBC, 0ebcH
$ce IMAGE_FILE_MACHINE_I386, 14cH
; . . . many more entries here . . .
END
which simply echoes all those undefined constants so I can put them in a file, NotInWindowsInc.inc.
Thanks for the clarification for the 'uninitiated'.
My idea of echo was only
"value of offset value of offset value of offset value of offset value of offset"
aside from using 'echo' on the command line. :smiley:
So basically its a macro 'thing'?
Would have been more apparent (what it does), if used in an example for 'macro noobz' like me. :tongue:

Can I ask you what compiller do you use ?

Assembler, not compiler. (Does a similar job but let's not confuse ourselves with wrong terms here.)

Ok, let's talk about what assembler.
So are you having problems with ml?
Quote from: NoCforMe on June 11, 2024, 03:34:20 AMSo are you having problems with ml?
Problems come when using on bounds... Now my problem is solved. I want to try another assembler and compare.

Bounds? as in array bound checking?
Just curious.

As bounds of assembler abilities. A default solution is the immediate value, but i need to get that from the expression of offsets.

masm isn't high level language, just with macro language additions.

Yes it is. By the assembly we write code as we need, but we also need to solve addresses and expressions automatic.
Quote from: Rockphorr on July 15, 2024, 12:02:44 AMYes it is [a high-level language]. By the assembly we write code as we need, but we also need to solve addresses and expressions automatic.
It's a mid-level language then: certainly higher than punching in raw opcodes in binary, but nowhere near as high level as, say, C++, where all kinds of calculations (addresses, array indices, structure selectors) are done for you behind the scenes.
Any way, we enjoy by the lea instruction :biggrin: :biggrin: :biggrin: :biggrin:

For asm programmers:
More freedom howto code ,but responsible for code adresses right or its buggy code instead of compiler automatically codes byte,word,dword/real4,qword/real8 arrays right
Ofcourse i could use masm way to code struct arrays if i want or take care of itself with manually code it
