Stop Watch With Batch Files

This is basically a stop watch for computers. It was "programmed" (if you can call it that) in simple MS-DOS commands. 

Simply copy and paste the following code into a text editing program, such as Wordpad, Notepad and Notepad++ and save it as "Stop Watch.bat"

Step 1: Code

Feel free to point out any mistakes I have made. This will also be going in my Mega Menu program once it is working fully. 

@echo off

echo Press 2 to record a lap (maximum of three laps)

P.S: I searched "images" on Google Images to find my last two photos. They are not mine, I do not claim they are mine. I have no right over them.

Step 2: Credit

If you wish to use this, like any of my tid-bits, you must do a series of things first:

1. Ask me for permission (I will say yes, but I want to know that your using it).
2. Give me credit for it in your program.
3. Send me a link or send me the program itself.

I am under the by-nc-sa license which states that you may use my program non commercially, so long as credit is given. 

Feel free to ask for help on a project.
