Command Description
The NETVIEW stage specifies to run a NetView, MVS, or VTAM command. The
resulting messages are placed in the pipeline. The NETVIEW stage can be placed
anywhere in the pipeline specification.
Streams
When NETVIEW is not a first stage, NETVIEW invokes a command once for each
message on the input stream. Each time NETVIEW receives a message on its input
stream, that message becomes the current message. The current message is the
message to which NetView's message information functions refer. Thus,
GETMLINE, MSGORIGIN(), DSIGETDS, or other message-dependent commands
and functions issued by the command invoked by the NETVIEW stage access the
message that caused the command to be invoked, exactly as they are if an
automation table action or a MSGREAD operation had produced the current
message. Also, NetView commands such as MSGROUTE that operate on messages
have access to this current message.
Unlike many other stages, the NETVIEW stage does not require an output stream.
This means that NETVIEW can be a last stage. Also, if a stage following is
disconnected, NETVIEW continues to process as long as it had an input stream.
Stream Type Number Supported
Input 1
Output 1
Termination Conditions
The NETVIEW stage terminates when it finishes processing its output or when the
input stream disconnects.
