Sending messages and commands through the network

Use the $D M command to send a message to a remote workstation operator, a console operator on another multi-access spool member, or to a console or remote workstation operator at another node.

To send a command through the network to an indicated system, use the $M n command (for communication between MAS members) or the $N n command (for communication between NJE node members). Identify the node and, optionally, the specific MAS member of that node to which the command text is to be sent. Both commands allow you to specify:

The MAS member and the node (by number or installation-defined name) to which the command text is to be sent.
The area and console identifier of the active MCS console at which the response to the command is to appear.

A command authority check is performed on all JES2 commands received from another node. The command authority defined for the sending node in the receiving node's node information table is used as the authority to govern all JES2 commands received from that node. Commands are ignored if the required authority is lacking. If the sending node is not defined as having network authority, job-related commands are processed to the extent in which they affect jobs in the system owned by the sending node. A node is considered to own a job if the job originated at that node or if the job's default print and/or punch output is for that node. (Use the $T NODE(nnnn),AUTH= command to set node command authority.)

If the command is not a JES2 command, the receiving JES2 passes the text to the operating system for processing (providing the sending node has network and system authority); however, no attempt is made to return MVS™ responses.
