4DOS - Computer Definition
An earlier command processor from JP Software, Inc., Chestertown, MD (www.jpsoft.com) that replaced the DOS COMMAND.COM file. It included enhanced commands that allowed multiple files to be referenced with a single command. For example, files with different names could be copied with one copy statement, rather than one statement for each file. 4DOS ran under Windows 95/98, while 4NT replaced the CMD.EXE file in NT and subsequent versions of Windows. 4DOS and 4NT were superseded by JP Software's Take Command family.
