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

Consider each stage in the PIPE to determine how the required four lines are
selected and returned.
Processing steps:
1. PIPE (NAME GETCONFG) starts the pipeline and gives the pipeline the name
GETCONFG.
2. VET NEXT ROWS returns the screen image shown in Figure 16 on page 316 to
the pipeline in the following multiline message:
BNH150I ROWS/NEXT OUTPUT FOR ’’ RECEIVED FROM MDMCNFG
NETVIEW NCF01 OPER1 11/16/10 11:55:13

Full-Screen Automation
The BNH150I message indicates the type of VET command used in the PIPE
and provides information about the attached command. The ROWS/NEXT
format returns the panel in the format as it is displayed on an operator's screen.
More information on BNH150I can be found in “Handling Returned Messages”
on page 324. Also, see the VET command information in “Interacting with
Virtual OSTs” on page 320.
3. CORRWAIT 60 causes the pipeline to wait up to 60 seconds for MDMCNFG to
build its panel on the virtual screen. The wait ends when MDMCNFG is ready
to receive input.
4. SEPARATE changes the multiline message returned by VET into multiple
single-line messages.
5. NOT TOSTRING /ALARM THRESHOLDS/ discards all lines up to the line
containing the string /ALARM THRESHOLDS/.
6. TOSTRING NOINCL /HIT ENTER/ selects all remaining lines of the panel up
to, but not including, the line containing the string /HIT ENTER/.
7. In Figure 18 on page 318 the selected lines are written to the CONSOLE.
8. The REXX EXEC terminates and the virtual screen running MDMCNFG is
automatically detached.
