This release of z/Server lets you start a z/Server user server as CEA-launched TSO address space, as a technical preview. A CEA-launched TSO address space is comparable to a TSO foreground session.
To use this functionality, the CEA system address space must be configured and running as a full function address space on the system.
The technical preview requires the JSON support for CEA under z/OS, which is available only from z/OS 1.13 and later.
In the current z/Server release, CEA-launched address spaces are only supported under z/OS 1.13.
