How to run 2 programs with Batch Commands

[Tally]

But I can run multiple COD2's on my laptop without this command. Or is it something else?

Actually, it is something else. After experimenting further, I found out that using allowdupe created some sort of wait time. And it was the wait time that was actually needed - not the expression allowdupe.

I ended up using this:

		@echo off

set color=04e
color %color%

mode con: cols=80 lines=30

goto START

:START
echo __________________________________________________________
echo.
echo "  _____                             __  __           _  "
echo " |  __ \                           |  \/  |         | | "
echo " | |  | | ___ _ __ ___   ___  _ __ | \  / | ___   __| | "
echo " | |  | |/ _ \ '_ \` _ \/ _ \| '_ \| |\/| |/ _ \ / _  | "
echo " | |__| |  __/ | | | | | (_) | | | | |  | | (_) | (_| | "
echo " |_____/ \___|_| |_| |_|\___/|_| |_|_|  |_|\___/ \__,_| "
echo "                                                        "
