Echo value of offset

[NoCforMe]

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.

[NoCforMe]

Well, it might have been kinda a dumb question.
But the say the really dumb question is the one you don't ask.

[Rockphorr]

Yes, exactly.
I didn't mean to bring this up to further muddy the waters.
So did you get everything to work OK?

So 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... 
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.

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 MACRO name:req, expression:req

.code


@Value @V_ofs,Some.Some_Method

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:

Code Select Expand

;====================================================
;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. 
So basically its a macro 'thing'?
Would have been more apparent (what it does), if used in an example for 'macro noobz' like me.

it's a lot more simple that your idea:

Code Select Expand

;=======[ STRUCTURE ]===============
Some\
STRUC
Some_Data_0\
BYTE ?
Some_Data_1\
BYTE ?
Some_Data_2\
WORD ?
Some_Method\
DWORD ?
Some\
ENDS


;======[ MACRO ]====================
@Value MACRO name:req, expression:req
 .RADIX 10h
 %ECHO @CatStr (<name>,< = >,%expression,<h>)
 .RADIX 0Ah
  ENDM

.386
.MODEL FLAT

.code

@Value @V_size,Size(Some)
@Value @V_ofs,Some.Some_Method

end

Can I ask you what compiller do you use ?

[Rockphorr]

I use ml of masm32 from masm32.com instead your UAsm64

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

Can you post the link to it ?

[NoCforMe]

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.

[NoCforMe]

So are you having problems with ml?

[Rockphorr]

So 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.

[NoCforMe]

Problems come when using on bounds...

Bounds? as in array bound checking?
Just curious.

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.
