Tony,
Speaking as a former vendor (a long time ago in a galaxy far, far away . . . ),
far be it from me to suggest that you give away valuable intellectual property.
That is contrary to all self-interest (never mind the enlightened kind), and I
would not ask or expect any vendor to do that.
Hi Folks,
The CBT Tape web site, www.cbttape.org, has just been updated with
CBT Version 496. The updates will (hopefully) now go to Version 497.
Please check the site to make sure things were done correctly, and all
the updates that were supposed to be there, are there. Thanks much

I would say that sometimes right after a feature comes out there is a
presentation at SHARE, e.g., "How to use the new PC-ss facility." That is not
