How Messages Are Routed

The destination of a particular message and the method used to send it depend upon the environment from which the message was issued.

• Messages originating in the product main address space are issued using the WTO (Write-To-Operator) macro instruction. These messages are routed to system consoles and to the system log. They also appear in the OPSLOG Browse component of OPSVIEW. The specific consoles upon which a WTO generated message appears depends upon routing codes. These are described for the WTO macro in the IBM manual z/OS V1R8.0 MVS Assembler Services Reference IAR-XCT, SA22-7607-11.
• Messages issued from the TSO-based components (such as the TSO command processor, OPSCMD) are produced using the PUTLINE macro. The destination of PUTLINE output is dependent on context:
  • Interactive TMP output is routed to a TSO terminal.
  • Messages issued from within a server address space are re-sent using the WTO macro instruction.
  • Batch TMP output is routed to the SYSTSPRT ddname.

Note: Using the OPSPARM command processor or the OPSPRM REXX function you can change the suffixes of some CA OPS/MVS messages. However, you cannot change the message suffix of severity R (reply) messages. A note under a message indicates whether the suffix of the message can be changed.
