What have I done wrong?

Hello Mikl__,

I guess some other modules are interfering. Can you send here the object module tut_02mp.obj producing an executable of 64000 bytes?

Hi, Vortex!

tut_02mp.asm contains this line.

include win64a.inc

How are defined the external functions in this include file? Normally, the API functions should be declared with EXTERNDEF otherwise your code will import a lot of unnecessary symbols making larger your object module. Disassembling tut_02mp.obj :

H:\masm32\bin\objconv.exe -fmasm tut_02mp.obj disasm.txt

The number of symbols defined with EXTERN is 1731. This the reason why you get a large executable.
