     BLF   Backup Large File

           this program will backup a large file from drives  ( c - k )
           to previously DD formatted diskettes on drives 'a' or 'b'.
           ( large file, in this case, means larger than 360 kb )
           it will write as much of the file as will fit on each
           diskette, and then ask for another, until it reaches eof
           on the input file.  use 'RLF' to restore the file.
