Thanks for letting me know you wrote this. I've added your name to the page
and the code. Some of the routines I collected before I knew I was going to
have a web site aren't credited and I'm happy to have that information now.

Hi,
here is the appropriate code fragment for your convenience.
BTW the 16-bit CRCUpd below is written by me, too.
