Running Block-Mode
Applications
Use the PROGRUN command to run local or remote block-mode applications such as
DSM/PM, T/Mail, OMF, and ViewPoint. The PROGRUN command suspends your
terminal output as long as the process is running. You can communicate interactively
with the application and receive the result of commands, but NonStop NET/MASTER
MS cannot intercept the exchanges with the process, and there is no record of the
responses to commands issued when you return to NonStop NET/MASTER MS. The
PROGRUN command can also be used to run conversational applications, but you
should restrict its use to block-mode applications (see the caution, below).
The Console Extras facility provides a user interface that facilitates your use of the
PROGRUN command. See “The Console Extras Facility,” later in this section.
When you start a program using PROGRUN, you must exit the program to return to
NonStop NET/MASTER MS. When NonStop NET/MASTER MS regains control of
the terminal, it returns you to the environment from which the PROGRUN command
was entered.
Caution You can run conversational utilities using the PROGRUN command. However, because applications and
utilities started using PROGRUN take complete control of the terminal and consequently suspend use of
the terminal by NonStop NET/MASTER MS, you are not aware of incoming messages destined for your
OCS window when you are interacting with a PROGRUN-initiated application. This impairs the integral
monitoring capability that NonStop NET/MASTER MS provides. OPSYS, therefore, is the preferred way
of starting and terminating interactive sessions with conversational Guardian utilities. For block-mode
applications, there is no choice but to use the PROGRUN command.
If you start a TACL process by using the PROGRUN command and then log on to TACL, you must press
CTRL-Y or use the EXIT command to return to NonStop NET/MASTER MS.
Be aware also that, if you start a TACL process by using PROGRUN and you do not have a valid
Guardian user ID and password, you will be unable to log on to, and stop, the TACL process to return to
NonStop NET/MASTER MS. In this case, you must ask your system manager to stop the TACL process
for you.
NonStop NET/MASTER MS queues messages arriving for display at a suspended
terminal. If a process retains control of a terminal for a long time, messages may be
lost. Such messages are still logged to the activity log.
If a terminal timeout occurs while a process has control of a terminal, the timeout
action is initiated when NonStop NET/MASTER MS regains control of the terminal.
