IBM Tivoli NetView for z/OS Programming: Pipes - IBM notice

2. The NETVIEW stage reads the pipeline messages and uses them as input to the
MSGROUTE command which sends a copy of the held messages to OPER3's
screen, where they are held also. The number of messages in the pipeline
affects how many times the NETVIEW stage runs. In this case, one message is
in the pipeline.
Note: The message that is displayed on OPER3's screen is only a copy and the
original held message is still displayed on ORIGOPER's console.
Example 2: Deleting Held Messages
This example shows how to use the HELDMSG stage with the CONSOLE stage to
delete held messages from an operator's screen:
PIPE HELDMSG | CONSOLE DELETE
Output showing existing held messages follows:

* CNM01 PIPE HELDMSG | CONSOLE DELETE
Processing steps:
1. The HELDMSG stage writes a copy of the held message queue to the output
stream.
2. The CONSOLE DELETE stage resets the hold status of messages in the
pipeline.
Notice that the vertical bar (|) has replaced the first characters of each line,
indicating that the message is no longer held.
Inserting Text into the Pipeline: LITERAL
The LITERAL stage enables the user to insert text into the pipeline.
Example 1: Inserting Text into the Pipeline
NetView Pipelines Device Drivers
This example shows how to use the LITERAL stage to add a message to the
pipeline and then display it.
