Explanation of the EXPAND command. It is EXTERNAL.

This command will expand a compressed MS-DOS 5.0 file.

Example:
       If you erase SORT.EXE on your hard drive, you just
       take the original DOS disks and find out where the 
       SORT.EX_ file is in one of the compressed files.
       After you do that you can do the following:
            expand a:\sort.ex_ c:\dos\sort.exe
