Altering a Terminal Definition
the priority at which the command interpreter is to execute. For more information about
these parameters, see the Safeguard Reference Manual.
For example, this command adds terminal $TFOX.#T015 and causes TACL to be
started after user authentication at the terminal:
=ADD TERMINAL $tfox.#t015, PROG $system.system.tacl
Use the INFO TERMINAL command to verify the results:
=INFO TERMINAL $tfox.#t015
The display shows:
The display shows that TACL is the command interpreter defined for this terminal. The
terminal is frozen because the terminal definition was just added to the Safeguard
database. To thaw the terminal:
THAW TERMINAL $tfox.#t015
Altering a Terminal Definition
Like other Safeguard protection records, an existing terminal definition record can be
altered.
For example, suppose you want to change the definition for terminal $TFOX.#T015 to
tailor the execution parameters for TACL. This command specifies that TACL is to
execute with a priority of 150 in CPU 4 and that $DATA2 is to be used as the swap
volume. The command also includes parameter text of 5, which TACL interprets as the
backup CPU number.
=ALTER TERMINAL $tfox.#t015, PRI 150, CPU 4, &
=SWAP $data2, PARAM-TEXT 5
Use the INFO TERMINAL command to verify the results:
=INFO TERMINAL $tfox.#t015
