NetView Pipelines Device Drivers
288 Programming: Pipes
PIPE LITERAL % JACK BE NIMBLE % | CONSOLE
Output from the pipeline using the LITERAL stage follows:
NCCF NETVIEW CNM01 OPER5 03/01/10 09:13:24
* CNM01 PIPE LITERAL % JACK BE NIMBLE % | CONSOLE
| CNM01 JACK BE NIMBLE
Processing steps:
1. The LITERAL stage writes the JACK BE NIMBLE text string to the output stream.
2. The CONSOLE stage reads its input and displays the message.
Example 2: Inserting Text Containing Command List Functions
This example, in a REXX command list named DISPOPID, shows how to use the
LITERAL stage to add a message containing a REXX function to the pipeline:
/* REXX COMMAND LIST - DISPLAY OPERATOR ID */
’PIPE LITERAL !My OPID is’, /* Add text to pipe */
OPID()’!’, /* Get my operator ID */
’| CONSOLE’
EXIT
/* Display to terminal */
Output from DISPOPID follows:
NCCF NETVIEW CNM01 OPER5 03/26/10 09:15:10
* CNM01 DISPOPID
| CNM01 MY OPID IS OPER5
Processing steps:
1. The LITERAL stage writes the MY OPID IS text string to the output stream
along with the REXX OPID function results.
2. The CONSOLE stage reads its input and displays the messages on the screen.
Example 3: Inserting Multiple Text Strings
This example shows how to use the LITERAL stage to add multiple text strings to
a pipeline:
PIPE LITERAL ? This is the CCC message ?
| LITERAL / This is the BBB message /
| LITERAL ! This is the AAA message !
| CONSOLE
Output from the pipeline follows:
NCCF NETVIEW CNM01 OPER5 05/02/10 10:40:10
* CNM01 PIPE LITERAL ? THIS IS THE CCC MESSAGE ? | LITERAL / THIS IS THE
BBB MESSAGE / | LITERAL ! THIS IS THE AAA MESSAGE ! | CONSOLE
| CNM01 THIS IS THE AAA MESSAGE
| CNM01 THIS IS THE BBB MESSAGE
| CNM01 THIS IS THE CCC MESSAGE
Processing steps:
1. The first LITERAL stage writes the CCC message text string to the output
stream.
2. The second LITERAL stage writes the BBB message text string to the output
stream in front of the CCC text already in the stream.
