See Chapter 2, “Pipeline Stages and Syntax,” on page 19 for information on pipe
stages.
Because MDMCNFG was attached by this procedure, without the ATTACH NAME
parameter, MDMCNFG automatically terminates when the procedure ends. You
can also terminate MDMCNFG explicitly using the DETACH command. For more
information about the ATTACH and DETACH commands, see “Attaching and
Detaching Virtual OSTs” on page 319.
Note: Additional examples can be found in CNME2011 and CNMS1101.
CNME2011 contains a SESSMGET example and CNMS1101 contains an
NPDA example.
The NetView program uses virtual operator station tasks (virtual OSTs or VOSTs)
instead of operator station tasks (OSTs) to present full-screen data to a program.
The VOST has a virtual screen where full-screen operations and subcommands of
the application running on the VOST can be run.
For information about valid subcommands for each NetView application, see the
NetView online help. The application name is included in parenthesis in the
heading of each subcommand description.
VOST virtual screens are 24 lines by 80 characters. All NetView operations and
subcommands that can be entered on a real 24-line by 80-character 3270 full-screen
terminal can be entered on a VOST virtual screen.
VOSTs are created using the ATTACH command. See “Attaching VOSTs” on page
319.
Dependent and Independent VOSTs
A VOST can be dependent or independent of its creating procedure group.
VOSTs, which are named when they are created, are independent of the procedure
group in which they are run. Independent VOSTs persist until specifically ended
using the DETACH command or until the command running on the VOST ends.
Unnamed VOSTs are local to the procedure group. When all components of the
procedure group terminate, the VOST terminates. Unnamed VOSTs can be
explicitly ended with the DETACH command.
