INTRODUCTION Page 1
────────────────────────────────────────────────────────────────────────
CheckCRC is a utility program distributed with Walt White and
Associates shareware. The utility verifies the integrity of the files
distributed with our products.
Data becomes corrupt for a number of reasons. Power failures,
noise during telephone transmissions, and computer viruses are just a
few examples. CheckCRC uses the Cyclical Redundancy Check or CRC method
of detecting errors. Prior to distribution an eight bit CRC and a
sixteen bit CRC-16 checksum are computed for each file. CheckCRC
computes a new checksum and compares it to the original. If they agree
the data is assumed correct.
USING THE UTILITY
────────────────────────────────────────────────────────────────────────
After copying the files CHECKCRC.DOC, CHECKCRC.CRC, CHECKCRC.EXE,
TMLINK.EXE, TMLINK.DOC, and REGISTER.DOC to the same drive and/or
directory, type CHECKCRC.
Assuming there are no errors, you will see the following screen:
CheckCRC (tm) (c) 1990 Walt White & Associates...
Reading -> CheckCRC.crc Complete...
Verifying -> CheckCRC.exe Correct....
Verifying -> TMLink.exe Correct....
Verifying -> TMLink.doc Correct....
Verifying -> CheckCRC.doc Correct....
Verifying -> Register.doc Correct....
If your screen matches the above example, you may delete the files
CHECKCRC.DOC, CHECKCRC.CRC, and CHECKCRC.EXE. You are now ready to
install TMLink. For instructions on installing TMLink, read TMLINK.DOC.

MESSAGE:
Reading -> CheckCRC.crc Not Found... **
** CAUSE: The file CHECKCRC.CRC was not found!
SOLUTION: CheckCRC will not run without the file CHECKCRC.CRC. Make
sure you have copied the proper files to the same drive and/or directory
where you are invoking CheckCRC ( see the file list above ).

Verifying -> TMLink.exe Corrupt.... **
Verifying -> TMLink.doc Correct....
Verifying -> CheckCRC.doc Correct....
Verifying -> Register.doc Corrupt.... **
CheckCRC Complete...
** CAUSE: The files TMLINK.EXE and REGISTER.DOC have been damaged!
SOLUTION: Files with the DOC extension aren't as crucial as files
with the EXE and CRC extension. If the damage isn't too serious you may
be able to decipher the errors, but we don't suggest it. You may be
missing some very important information!
Files with the EXE and CRC extension are crucial! If you receive a
message stating that one of these files has been damaged, DON'T USE IT!
Delete the files from T_M_LINK and start again. If you have received
TMLink via download and experienced errors during transmission, try
again.
You can order a registered version of TMLink from Walt White and
Associates. Read the Registration section of TMLINK.DOC or REGISTER.DOC
for details!
