You can test your copy of the distribution diskette, to make 
         sure the copy is accurate, by entering the command CHECK *.* 
         at the DOS prompt.  The output should look like this: 


CRCK ver 4.2B (MS DOS VERSION )
CTL-S pauses, CTL-C aborts

--> FILE:  LW      .COM         CRC = 1E 42

--> FILE:  CONFIG  .COM         CRC = D9 18

--> FILE:  MANUAL  .            CRC = BA C3

--> FILE:  READ    .ME          CRC = D7 99

--> FILE:  SUPPORT .            CRC = 8D 15

--> FILE:  SAMPLE  .ADR         CRC = 1E FC

--> FILE:  SAMPLE  .            CRC = B9 AF

--> FILE:  CHECK   .COM         CRC = BD 22

--> FILE:  CHECK   .TXT         CRC = unknown

 ---------------------> SUM OF CRCS = unknown

DONE
         
                  
         Note: the CRC for CHECK.TXT will be incorrect as will be the 
         total, because you cannot write a file's CRC to the file 
         without altering the CRC of the file.
