Disc Operating System 4.0 Reference

Here is a reference guide for Disk Operating System version 4.0 from the authors of "The New DOS 4.0". The seven sections describe how to name files and directories, use DOS via the new DOS shell or the traditional command line, create and use batch files, edit files with the EDLIN line editor, use the FSDISK utility to partition your fixed disk, and use the DOS filters and DOS file redirection feature. Extensive appendices describe the function keys that can be used with the DOS shell or command line.
