z/VM Systems Communicating with z/OS

Use z/OS format control files if one or more systems in your MIMplex is a z/OS system. Your z/VM system can, and should, use CMS format for checkpoint files, however z/OS systems cannot access CMS or CMSFP format control files.

A z/VM system cannot allocate z/OS format control files. Control files that are in z/OS format must be allocated using a z/OS allocation method.
