Processing steps for first pipeline:
1. The NETVIEW stage processes the display of the remote domain information,
however instead of displaying the messages, they are placed in the pipeline.
2. The CORRWAIT stage allows 10 second intervals between each message
returning to the pipeline. If the 10 second duration is exceeded, no more
messages are placed in the pipeline.
3. The CONSOLE stage reads the messages from the pipeline and displays them.
4. The SAFE stage reads the messages from the pipeline, and writes them to a
message queue named HOLDMSG.
Processing steps for second pipeline:
1. The SAFE stage reads the messages, which is one MLWTO, from the queue
named HOLDMSG and writes them to the pipeline.
2. The SEPARATE stage breaks the MLWTO into single-line messages.
3. The LOCATE stage selects messages containing the text string 'ACTIV'.
4. The CONSOLE stage reads the messages from the pipeline and displays them
on the screen.
