im getting this error msg.. dunno wat to do...

Linking...
LINK : error LNK2001: unresolved external symbol _mainCRTStartup
C:\Documents and Settings\Racer\Desktop\temp\hw1.1\Debug\hw1.1.exe : fatal error LNK1120: 1 unresolved externals
hw1.1 - 2 error(s), 0 warning(s)
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========

Im suppose to do a inverse of x into y, then sum all the number in y, and put result into z, if anyone know my 2 errors, that be great too, thanks

include irvine32.inc

.data
X   SDWORD    -3000, -2000, -1000, 0, 1000, 2000, 3000
Y   SDWORD   7 DUP (?) 
Z   SDWORD   ?

.code
begin:
lea eax,x
lea ebx,y
lea edx,z
mov ecx,7

next:

;pushing x into a stack
push [eax]
add eax,4

;pop the stack and store to y
pop [ebx]
add ebx,4
loop next


mov ecx,7
;sum all

next1:
add ebx,4
loop next1

;stores into z
mov edx,ebx


end

Your linker wants to link against the C runtime startup function. You need to do something else, depending on what it is you want.
1) If you're writing just a single function in ASM, you need to avoid calling the linker. Pass the assemble-only flag to MASM or something.
2) If your assembly is a complete program that does not use the CRT, you need to set the entry point to your own. I see no such code here, though.
3) If your assembly is a complete program that uses the CRT (even just having a main() function counts), you need to link against the CRT.

If you include "irvine32.inc" i would say that "irvine32.lib" is missing. This will generate such messages.

include irvine32.inc
includelib irvine32.lib

yea, that is solve but another problem pop up . i build it and went fine. when i went to debug it, it say... any ideas??

'hw1.1.exe': Loaded 'C:\Documents and Settings\Racer\Desktop\temp\hw1.1\debug\hw1.1.exe', Symbols loaded.
'hw1.1.exe': Loaded 'C:\WINDOWS\system32\ntdll.dll', No symbols loaded.
'hw1.1.exe': Loaded 'C:\WINDOWS\system32\kernel32.dll', No symbols loaded.
The program '[2276] hw1.1.exe: Native' has exited with code 0 (0x0).

ahh why can't my first assembly program go well .

It starts and ends with a success code. Looks like your entry function is empty.

[minor28]

You have not shown all code so it is difficult to say. I suppose "begin:" is the entrypoint which mean the code ends with "End begin".

You also have API ExitProcess with argument 0

push 0
call ExitProcess

There you have the message "has exited with code 0 (0x0)."

It seems to be OK. To debug with debugging information you must assemble and link your code with debug options.

I can't see the problem.

I don't know what you do with irvine32.dll but if you want to se the result of your calculation you can do it like this.
