Any version of my program not flying

[Camper]

Hi,

I was trying to get a grip on type conversions in MASM, but my program is always crashing.
I was wondering if somebody can help me out?

Code Select Expand


include \masm32\include\masm32rt.inc

.data
MyWord Word 123
MyResult Word 4

.code
start:

this proc
mov eax,MyWord
mov MyResult, eax
ret
this endp

call this

printf("MASM:  %u\n",MyResult)
printf("\n\n")

exit0:
        inkey
        exit
end start

"this" is a reserved word (see doc), so you must first rename the proc. Also, you start label is placed in such way that the program execution starts with proc "this".
The defined variables does not match the register size (16 bit vs. 32 bit).

Build this with "console assembler and link"

; ------------------------------

    include \masm32\include\masm32rt.inc

; ------------------------------

  .data
     MyWord DWORD 123
     MyResult DWORD 4

    .code

; ------------------------------

start:

call thisproc

    printf("MASM:  %u\n",MyResult)
    printf("\n\n")

    inkey
    exit

; ------------------------------

thisproc proc
  mov eax,MyWord
  mov MyResult, eax
  ret
thisproc endp

; ------------------------------

end start

Thanks Hutch, Thanks qWord, I managed with this   Have to learn visit the masm32 compilers debugger, instead of VS code.
Is this a misconception with the register size, it looks more like a 32/64 mismatch, right?

I came up with this,

Code Select Expand


include \masm32\include\masm32rt.inc

.data
MyWord DWord 123
MyResult DWord 4
.code

Module1 proc
mov eax,MyWord
mov MyResult, eax
ret
Module1 endp

start:
call Module1
printf("MASM:  %u\n",MyResult)
printf("\n\n")

exit0:
        inkey
        exit
end start

From the reversed order of your code, it looks like you used to write code in TASM. There is no reason to do this in masm.

Ever heard of a program called SynthMaker?

word=16 bits
dword=32 bits its 16/32 bit mismatch
qword=64 bits
