PAUSE Command
PAUSE Command
You can run more one or more processes simultaneously from within your TACL
process. Use the PAUSE command to cause TACL to wait for prompting from-or
completion of-another process.
\node-name
is the name of the system where the process identified by $process-name or
cpu,pin is running. If you omit \node-name, the current default system is used.
$process-name
is the name of a process for which TACL is to pause. TACL does not prompt for
commands until it receives a process deletion message from that process.
cpu,pin
is the CPU number and process identification number of a process for which TACL
is to pause. TACL does not prompt for commands until it receives a process
deletion message from that process.
Considerations
•
PAUSE with no parameters causes TACL to pause for the last process started
from the current TACL, or the process for which TACL last paused, if that process
is still running.
•
If the process is interactive, you can exit the process and regain control of your
terminal by pressing the BREAK key.
•
When you enter a PAUSE command, the current TACL process stops prompting
for commands, allowing the specified process (or the default process) to gain
control of your terminal if it needs to use it for communication. When the other
process finishes, or is deleted, the operating system sends a process deletion
message to TACL. When TACL regains control of your terminal, it resumes
prompting.
Assume, for example, that another process controls your terminal, and you press
the BREAK key to regain control of the terminal. To return control to that other
process, enter PAUSE. TACL regains control of your terminal after that other
process finishes or is deleted.
•
To list the processes that are currently running on your terminal, use the STATUS
*, TERM command. If a process has a name, you can include its cpu,pin in a
PPD command and obtain its $process-name.
•
You can use the WAKEUP command to specify the action TACL takes when it
receives a process deletion message.
