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

PIPE NETVIEW MVS D A,L | CORRWAIT 5 | TAKE 1 | CONSOLE
Output from the pipeline follows:

Processing steps:
1. The NETVIEW stage invokes the MVS command and places the corresponding
response messages in the pipe.
2. The CORRWAIT stage allows 5 seconds for each message to return from MVS.
Note that MVS is actually a NetView command which sends command text to
the MVS system. Use CORRWAIT when sending commands to other
applications, such as VTAM or MVS, to allow enough time for a response to
return.
3. By selecting the first message, the TAKE stage imposes early termination of the
CORRWAIT stage.
4. The CONSOLE stage reads the messages and displays them.
Example 2: Generating a Return Code from the NETVIEW Stage
This example shows how the MOE option with the NETVIEW stage generates a
message containing a return code. The command, NONESUCH, is purposely
incorrect.
PIPE NETVIEW MOE NONESUCH | CONSOLE
Output from the pipeline follows:
NCCF NETVIEW CNM01 OPER6 05/17/10 17:05:01
* CNM01 PIPE NETVIEW MOE NONESUCH | CONSOLE
- CNM01 DSI002I INVALID COMMAND: ’NONESUCH’
- CNM01 DWO369I NETVIEW STAGE (1) HAD RETURN CODE 4
Processing steps:
1. The NETVIEW stage runs the NONESUCH command and places the messages
in the pipe.
2. The CONSOLE stage reads the messages and displays them.
Example 3: Acting on Pipeline Data
This example shows how to use the NETVIEW stage to process data incoming to a
command through the pipeline. In the following example, an operator named
ORIGOPER sends a message to another operator named OPER6.
