to that device. So far

Lindy,
What are you trying to do ?
The BIG picture... not the story of trying to be a Virtual Device in zOS
because there is other ways of doing the same thing, that will cost you much

and examples on the Share tape.
.
Anyway, it's a good start. Thanks GP.

How this can be a patent I don't understand. I thought patents were for
inventions, and copyrights were for software.
Software patents do exist.
Some are considered inventions.
As a matter oif fact, parts of the open sores community is trying to get
software patents disallowed.

What is your overall objective ?
Are you trying to write an Operating System or are you just trying to
ask an intelligent question on an IBM email list because the SAS
