Programming Interface Information:
These web pages primarily document information that is NOT
intended to be used as a Programming Interface of z/VM.

These web pages also document intended Programming Interfaces
that allow the customer to write programs to obtain the services
of z/VM. This information is identified where it occurs by an
introductory statement.
