A new version of CODEC is created. This version isn't compatible with previous one.
In the furture the program will be always compatible with published versions.
The new version generates more user information to the screen and CRC calculation has been speedup.
Important is:

• after discovery of changes to file the output file will be automatically cleanup. So the code will not be available.
  
• the program can not be terminated by a CTRL-BREAK command.
  

Greetings.
