Does anyone have a copy of the above code?

MAK - Not exactly, but poking around www.archive.org it seems that www.hks.net started redirecting to pages at redhat.com somewhere around 2001, and searching redhat.com for CCVS comes up with a number of links (no idea if it's the same thing), some of which imply a license key may be required for it to operate in other than a demo capacity.

CM - I guess this page: http://freshmeat.net/projects/ccvscreditcardverificationsystem/ indicates where (ftp server) to find it, but as someone mentioned it is definitely a proprietary application from RedHat (not free software at all).

LV I'm not certain that the above catalog entry was supposed to indicate a free software package. P.S. that freshmeat pointer is also stale. At least it is not just the Tcl community with stale URLs.
