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

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

--> FILE:  LW      .COM         CRC = 3A 79

--> FILE:  ME      .ME          CRC = 50 C4

--> FILE:  END     .            CRC = 00 00

--> FILE:  MANUAL  .            CRC = FB 11

--> FILE:  READ    .ME          CRC = 8F FB

--> FILE:  SUPPORT .            CRC = 56 9E

--> FILE:  SAMPLE  .ADR         CRC = 9B AA

--> FILE:  SAMPLE  .            CRC = FC 5A

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

--> FILE:  CHECK   .TXT         CRC = unknown

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

DONE



         The reason why the check.txt file is unknown is because the 
         above information is added to it.  Therefore, the sum will 
         also be unknown.
