How Can I Tell if 4DOS Is Running?
4DOS is a replacement command-line interpreter for the Windows95/98 and Windows ME operating systems. Once installed, 4DOS transparently replaces the Microsoft DOS command-line interpreter. Determining whether a command-line window is running MS-DOS or 4DOS can be difficult just by looking at the screen, as both programs present you with a standard "C:" prompt when started. However, you need only one command to verify which program is running.
