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

The simple pipeline FAN:FANIN|LABS: passes the data to COLLECT in the order
the streams were defined. This allows color or other processing to be done on the
message prior to the COLLECT stage.
By adding DEBUG you see the connection flow within the pipeline.
/* REXX Example */
address NETVASIS,
’PIPE (NAME TASKLIST END \)’,
’| NETV LIST STATUS=TASKS’, /* generate the data */
’| DROP LAST 1’, /* no need of "END OF DATA" */
’| COLOR GREEN’, /* standardize buffers */
’| EDIT WORD 2 1’, /* reformat data from the lines */
’19.8 8’,
’38.8 19’,
’55.* 35’,
’| LABS: COLLECT’, /* data and labels, labels first */
’| CONSOLE ONLY’, /* display results */
, /* --- END of simple pipeline, begin new pipeline..*/
’\ FAN: FANIN’, /* feed data to "LABS", in order */
’| LABS:’,
, /* --- END of simple pipeline, begin new pipeline..*/
’\ LIT !-------- Status of NetView Tasks ---------!’,
’| COLOR YEL’, /* Control line becomes yellow */
’| FAN:’, /* give to "FAN" (primary input) */
" LIT !Task Task’s Taskname or Current!",
’| COLOR PINK’, /* First label line becomes pink */
’| FAN:’, /* give line to "FAN" (2nd input)*/
"\ LIT !type D Resource Status!",
’| COLOR PINK’, /* Second label line becomes pink. */
’| FAN:’ /* give line to "FAN" (3rd input) */
Example: Formatting MVS D A,L Output
In the following example, each new output line contains information about only
one job. The original three label lines are still label lines.
The source for this example is in CNMS1101.
/* REXX Example */
’PIPE (NAME DISPAL END \)’,
’| CORRCMD MVS D A,L’, /* generate data */
’| SEPARATE’, /* handle lines individually */
,/* SEP preserves the line type (ctl, label, data, end) */
’|A: TAKE 3’, /* first 3 to primary, rest 2ndary */
’| COLOR WHITE’, /* Ctl & label become white */
’|Z: FANINANY’, /* all lines return here... */
’| COLLECT’, /* collect all lines, preserve type*/
’| CONSOLE ONLY’,
’\ A:’, /* data lines come here... */
’|C: CHOP 35’, /* left side to primary, rest "C" */
, /* CHOP also preserves the line type */
’| COLOR BLUE’, /* some data becomes blue */
’|Z:’, /* give in back to FANINANY */
’\C:’, /* right side of data comes here */
’| COLOR TUR’, /* other data becomes turquoise */
’|Z:’ /* give in back to FANINANY */
