Message formats

The message format of all messages is determined by the destination specified in the USS table.

In pre-Version 4 releases, messages sent to the primary program operator log (PPOLOG) or percolated to a primary program operator (PPO) are copies of messages formatted for the system console or secondary program operator (SPO). In the current version, copies of messages are no longer sent. Messages appear in the format defined in the USS table for the message destination.

The impact to automated operation procedures depends on which USS table is specified for your system console and each program operator application (POA), and whether those tables define messages with or without blank suppression.
