A security program for your (second-) favorite 80x25 screen. It was designed to be launched from the autoexec.bat, and can check users against a list of those allowed to use the computer. Comes with fancy ASCII windows at no extra charge. Of course, if you're savvy, you also know you can bypass this by holding down the left shift key on boot, or by pressing ctrl+c to kill the current program in DOS. But most people even back then didn't know that. Written in Quick Basic 4.5.
