Anyone know what's wrong with my program?

It doesn't even output anything to the screen, for some reason.

.386 

.model flat, stdcall 

option casemap:none 

include \RS\include\ifiles.inc 

.data 

.data? 

string1                           DB  512 dup (?) 

i1                                DWORD ? 

i2                                DWORD ? 

i3                                DWORD ? 

i4                                DWORD ? 

hFile                             DWORD ?
