4DOS 8.0

4DOS is a command interpreter or "shell." That means that it displays a prompt, waits for you to type something, and then reacts to your commands.
4DOS was designed so that you don't have to change your computing habits or unlearn anything to use them. If you know how to display a directory, copy a file, or start an application program from a command prompt, you already know how to use our command interpreters.
4DOS supports every command you already know, add to the features of each command, and add dozens of new commands.
