Batch Programming (slightly Advanced)

hello, first off i would like to say that if you are new to batch programming then you might want to go to an easier link for the basics, anyway, this is a code i wrote that i thought was kinda nifty, though it may seem like a ripoff of someone elses i assure you that i wrote it myself.
