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:  READ    .ME          CRC = 7E 84

--> FILE:  MANUAL  .            CRC = 02 3E

--> FILE:  SUPERCOM.COM         CRC = 38 3C

--> FILE:  DIAL    .COM         CRC = 6C 0B

--> FILE:  DIALADD .COM         CRC = ED 34

--> FILE:  DIALDEL .COM         CRC = 5F 8E

--> FILE:  DIALSHOW.COM         CRC = AA 17

--> FILE:  SUPPORT .            CRC = B4 81

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

--> FILE:  CHECK   .TXT         CRC = 19 E2

 ---------------------> SUM OF CRCS = A7 67

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 that file.
