Re: About Rand Function
You can use the C lib's rand. There's a function nrandom in masm32.lib, maybe you can use it.

Use the 'Search' function and you will find a variety of code and techniques with their pros and cons.

Here is an example :

.386
.model flat,stdcall
option casemap:none

include \masm32\include\windows.inc
include \masm32\include\kernel32.inc

includelib \masm32\lib\kernel32.lib
includelib \masm32\lib\msvcrt.lib

printf PROTO C :VARARG
rand   PROTO C

.data
output  db 'Random number: %d',13,10,0
counter dd 10

.code

start:
        call init
@@:
        invoke  rand
        xor     edx,edx
        mov     ecx,20
        div     ecx
        invoke  printf,ADDR output,edx
        dec     counter
        jnz     @b
        invoke  ExitProcess,0

init PROC
        local   _st:SYSTEMTIME
        local   temp:DWORD
        invoke  GetSystemTime,ADDR _st
        xor     eax,eax
        mov     ax,_st.wMilliseconds
        push    eax

Checkout http://www.asmcommunity.net/board/index.php?topic=21695.msg164351#msg164351, where I've posted the code for a random number generator.
