Product Overview:

The VTAM Multi-User Platform (VTAM MUP) provides program services for multiple users per address space and multiple address spaces in a native MVS VTAM environment. Automatic SAF calls provide security processing at the same level as TSO. The VTAM MUP provides a high performance TSO-like environment without the high overhead of native MVS TSO.
The VTAM MUP supports the SSR Server and FSE+ applications from ASI. A batch job to initiate SSR Server transfers is included with the SSR Server version of the VTAM MUP.

One or more workstations are acquired and optionally logged on to the SSR Server application executing under the VTAM MUP. The batch job then instructs the workstations to perform one or more file transfers to or from the host. All SSR Server functions are available in the VTAM host-initiated environment. The VTAM MUP and its API are available for OEM customers. The API enables applications to interface with the MUP terminal I/O and storage management routines. Additional information is available upon request.
