:This is the public domain program CRCK. I have included it to
allow you to verify the correctness of the various files on these
disks. the file CHECK.LST contains the correct check number for all
files on these disks.
The program CHECK.COM is used to compute and display the 'checksum'
for the file specified with it, i.e.. CHECK [drive:]<filename.ext>
You can use this to show the checksum for a file before and
after transfer, they should match, giving some assurance
that the transfer is good.
Wildcards such as '*' and '?' can be used in the command line.
Adding a sub-command 'F' after the filename.ext will cause a
file CHECK.LST to be written to disk.
Example : CHECK *.* F
CHECK B:A???.COM
The checksum is based on the CCITT standard polynomial
X^16 + X^15 + X^13 + X^7 + X^4 + X^2 + X
