Notepad logo:

I have a computer but it is newer and doesn't feature the Command Prompt or the MS-DOS software. What you could use is Notepad. Notepad should be installed into every computer by now. Mines is here:

Use that to code with MS-DOS.

After you are done, save it. But make sure you name it a .bat file. Example: Game.bat. When you name it .bat, it represents a Windows MS-DOS batch file.

Now you try! It %100 works!

(Sorry for the poor quality. Let me know if it works for you)
