system_command

A valid TSO system command or CLIST name that does not require a parameter.

Usage notes

• No parameters can be specified as part of the system command or CLIST invocation. To execute noninteractively when parameters are required, you must enter the complete invocation in a CLIST and then use a TSO or SYSTEM command to call that CLIST (without parameters).
• You cannot introduce a new Debug Tool session using the SYSTEM command.
• When operating interactively in TSO, there is no provision for entering a mode where commands are accepted repeatedly; however, it is possible to write your own such iterative sequence in a CLIST.
• You cannot issue CICS® commands using SYSTEM.

Examples
