   Apparently you have misunderstood me. You were saying that if nowadays
(i.e., when PKNDRIVER already exists) someone were to develop CCS support
for VMS on KA410, he/she would have to modify TVDRIVER and that would be a
lot of work. I was saying that since PKNDRIVER already exists, it would
take very little work to make it work on KA410, and I suspect that the only
work required would be to remove some blocking code.

   Sure! Send me a copy of the listings.
