Running A Process At A High Pin; Your Default Process; Interrupting A Process - HP Guardian User Manual

Starting and Controlling Processes With TACL
An explicit RUN command includes the keyword RUN followed by the name of the
program file:
5> RUN $SYSTEM.OPERATE.SWAPURGE
If you do not include the volume and subvolume, the TACL program expands the
file name using your current defaults.
An implicit RUN command includes the name of the program file, without the
keyword RUN:
6> TEDIT
If you specify a partial file name in an implicit RUN command (as for TEDIT in this
example), the TACL program does not expand the file name. Instead, it searches for
the program on $SYSTEM.SYSTEM. If the TACL program cannot find the
program there, you receive an error. (You can include #PMSEARCHLIST in your
TACLCSTM file to tell the TACL program to search in your defaults; see
Defining Function Keys and Writing

Running a Process at a High PIN

Using high process identification numbers (PINs) lets you concurrently run more
processes. High PINs have values above 255; low PINs have values from 0 through 254.
Because some processes and devices must run at low PINs, you might want to run an
application at a high PIN if there is a shortage of low PINs. To run the application
ACCOUNTS at a high PIN, enter:
7> RUN ACCOUNTS /HIGHPIN ON/
HIGHPIN ON specifies that the program will run at a high PIN if the HIGHPIN flag is
set in the object file (and library file, if any) and if a high PIN is available. For more
information about running a program at a high PIN from the TACL program, see the
TACL Reference Manual.

Your Default Process

When you start a new process, the TACL program stores the process name, its CPU, and
PIN in a special buffer that holds one process name and number at a time. This buffer
identifies your default process.
If you enter a process-control command (such as PAUSE, ACTIVATE, STOP, and
SUSPEND) but do not specify a process name or CPU and PIN, the TACL program
assumes that you are referring to the default process. The default process is cleared
when that process terminates.

Interrupting a Process

Use the Break key to interrupt a process and return to the TACL program. When you
press Break, most processes yield control of the terminal to the TACL program and
continue to run in background mode. If a background process requires input from or
