Using MVS system symbols in TCPIP.DATA

For ease of management when configuring a complex environment, use MVS™ system symbols such as &SYSCLONE, &SYSNAME, and &SYSPLEX. The resolver translates these symbols as it reads TCPIP.DATA, reducing the number of TCPIP.DATA files that must be maintained in a multisystem environment. For detailed information about symbols and how to define them, see z/OS MVS Initialization and Tuning Reference.
