Processing steps:
1. The NETVIEW stage executes an MVS command and writes the messages as an
MLWTO to the output stream.
2. The CORRWAIT stage allows a 20 second wait for messages to be returned
from MVS, resetting the timer as each message is received.
3. The SEPARATE stage reads the input stream and splits the MLWTO into
single-line messages.
4. The CONSOLE stage reads the input stream and displays the messages on the
screen.
Note: If the SEPARATE stage is not used, the pipeline output looks similar to the
following example:

Building an MLWTO: COLLECT
The COLLECT stage enables the user to create a single MLWTO from the messages
in the pipeline.
Example: Building an MLWTO from Single-Line Messages
This example shows how to use the COLLECT stage within the PIPE command to
gather the messages output from the LIST '' command, into an MLWTO:
PIPE NETVIEW LIST ’’ | COLLECT | CONSOLE
Output from the pipeline looks similar to:
