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.

Scroll to and choose the control block you would like displayed. If the control block you choose is part of a larger control block, the larger is displayed.
