error A2071: initializer magnitude too large for specified size

[pgw001]

Hi all,  need some guidance in understanding how to make further progress

I am trying to invoke a procedure but the assembly fails with the A2071 error pointing at the last line (endp) of the procedure.
Attempts to comment out the bulk of the code is not helping and I am not sure what I am looking for ? The logic is not complete
as I cannot proceed without the ability to assemble - code specifics follow:

readrec PROTO :DWORD

        invoke readrec, offset recout

   mov hFile, fopen("testIN.asm")            ; open the input file
        mov flen, fsize(hFile)                      ; get its length
   mov hMem, alloc(1024+1)                  ; allocate a 1k plus '0' buffer
   mov eax, outbuf                        ; store passed line buffer
   mov lbuf, eax                        ; store passed line buffer
   mov inPtr, 0                        ; reset input buffer ptr
   mov otPtr, 0                        ; reset output buffer ptr

labRD:
   mov cloc, fseek(hFile,cloc,0)            ; save next file pointer
   mov bwrt, fread(hFile,hMem,1024)         ; read data from file into buffer

   mov edi,outbuf                        ; setup output line buffer

[GoneFishing]

your code compiles just fine here
How  does the complete asm file being assembled  look like ?

[pgw001]

Many thanks for the prompt and thought provoking response.

Just to be clear are you saying that despite the assembler pointing to this proc as being in error
the actual problem could be elsewhere in the code?

Best,

[GoneFishing]

As far as I've been able to compile it without warnings I thought that the actual problem lies outside this proc

[jj2007]

your code compiles just fine here

Well, it doesn't, it throws plenty of errors - probably because the OP assumes that real experts like vertograd have nothing better to do than adding header stuff etc to his code.

include \masm32\include\masm32rt.inc

.code
start:
[OP's code]
end start

If you want feedback, post COMPLETE code.

JJ, as I already wrote the code compiles fine HERE  (you're not here, are you?)  ;)
Really I'm not an expert and therefore I found some time to add all missing stuff and successfully assemble it .

[EDIT]: BTW I used ML 6.14 AND THE LATEST MASM32 PACK

Hi pgw001,

I am trying to invoke a procedure but the assembly fails with the A2071 error pointing at the last line (endp) of the procedure.

Error A2071 is this. You should post the entire code for qualified help.

You might shows us the full error message? I guess the problem resist inside gwMacros.inc.

[pgw001]

Folks, just to clarify some recent responses:

I don't think the additional macro's file has any bearing on the problem - it is not referenced in this assembly

The full error message is contained in the subject line

I stress the code does not represent a finished product, it is a test harness that I cannot get to assemble

Thanks,

[qWord]

The above code assembles fine after removing "include gwMacros.inc".

[GoneFishing]

it assembles here too
may it be ML / masm32 sdk version issue ?

[jj2007]

The full error message is contained in the subject line

Perfect. If you could now kindly tell us in which line that error happens, then we might have a chance to find that bug.

Without the macro include, it assembles fine and crashes here with an access violation:

004010FB     ³.  8B7D 08           mov edi, [ebp+8]
rdLine       ³>  8A06              Úmov al, [esi]
00401100     ³.  46                ³inc esi


Probable reason: testIN.asm is not on my computer, and there is no error check after fopen.

[dedndave]

it may be the missing spaces in 2 places

Code Select Expand

mov[edi],al

Code Select Expand

mov [edi],al

another possibility is that macros.asm might be better included last
so that all the functions used in the included file are prototyped prior to reference

[pgw001]

Folks,  many thanks for the suggestions

I have commented out the include statement for gwMacros.inc

I have made the include statement for macros.asm the final include item

I have corrected the mov instruction syntax errors, sadly the assembly still fails as follows:

Error   1   error A2071: initializer magnitude too large for specified size          X:\MASM\fileopsr.asm    171    1   Project1

The line no identified (171) points to the - readrec  endp  statement
